Sounds like you're suffering from this: http://forums.maplestory.nexon.net/discussion/151/memory-dll-corruption

Also sounds like you're using Windows 8 or higher. Normal restart won't always work, so you'll have to do a full restart, as explained here: http://www.howtogeek.com/129021/how-to-do-a-full-shutdown-in-windows-8-without-disabling-hybrid-boot/

Apparently the Limitless patch got a little ahead of themselves because in addition to implementing changes from this patch, excluding the 5th Job Advancement and the Arcane River, they also implemented changes from these two excluding their Arcane River areas.

As a result, there are undocumented changes from the Chu Chu Island patch and the Lachelein patch as well as many changes from the Vanishing Journey patch that weren't mentioned.

These changes include:

Damage Range now caps at 100 million (Good luck with that), the detailed stats UI now shows your Damage stat and your Final Damage stat, and Final Damage now counts toward your Damage Range

Status Resistance now reduces the duration of Abnormal Statuses received by a percentage and caps at 500

Defense now caps at 100k

Fighting monsters that are higher leveled than you will now induce a Final Damage penalty (2% per level in non-Reboot worlds, 10% per level starting at 10 levels higher than you in Reboot world)

Level difference affecting your EXP gained has been modified (Bosses unaffected)

Monsters can no longer dispel (i.e. remove your buffs)

Certain enemy attacks no longer bypass invincibility skills

Most monsters that were immune to binding skills are no longer immune to them, but monsters' resistance to binds after being binded now last longer

Demon Avenger's HP gained from leveling up, advancing, investing AP, equipment, and Rage Within have been cut in half (percentage boosts are unaffected), but their primary stat now gives their damage range twice as much damage as before and their Hyper Potion Mastery's recovery multiplier has been decreased from x3 to x2, but it now applies to Elixirs and Power Elixirs

The following content no longer have a level limit:
Tangyoon’s Cooking Class
Romeo and Juliet
Chryse
Nett’s Pyramid
Dimensional Crack
Pirate Davy Jones
Devil Balrog

The following content is now instanced:
Tangyoon’s Cooking Class
Horntail (Easy, Normal, and Chaos)
Hilla (Normal)
Easy Zakum
Chryse
Nett’s Pyramid
Dragon Rider
Escape
Kenta in Danger
Dimension Invade

Following bosses have been added to Murgoth’s Soul Collector:
Captain Black Slime
Xerxes
Rex
Pianus
Dragon Rider
Lucid

The following skill changes have been implemented:
From the Vanishing Journey patch
Hero's Will now works on additional status effects (e.g. transformation debuff)
Summon skills now show their durations as buff icons and can be cancelled by right-clicking their icons
Binding skills' base durations have been decreased, but duration can be increased based on how much damage they deal up to +100%
I/L Archmage's Freezing Breath and Shade's Spirit Trap now deal damage
When using Roll of the Dice, if you get a 1, the cooldown for the next roll will be cut in half
Monsters hit by Shade's Soul Splitter will now resist the splitting effect for a certain period of time
Demon Slayer's Binding Darkness no longer has a DoT
Angelic Buster's Pink Pummel now travels shorter
Angelic Buster's Star Gazer now stacks with Sharp Eyes
Kinesis' Psychic Assault's DoT damage boost now has a maximum cap
From the Lachelein patch

Paladin's Heaven's Hammer - Cooldown Cutter's cooldown reduction has been decreased to 30%
Bowmaster's Focused Fury's cooldown has been removed
Night Lord's Shadow Web's jump height has been decreased
Dawn Warrior has a new 4th job skill called Equinox Slash. When used, you attack and move forward a distance. Can only be used while in the air and while Equinox Cycle is active. Can be used while using other skills. Has a 6 second cooldown. This skill does not require SP and instead gets leveled up by leveling up Equinox Cycle. (This skill is a lot like Mercedes' Spirit Nimble Flight)
Dawn Warrior's Styx Crossing's attack range has been increased, its cooldown has been decreased to 30 seconds, fully charges faster, you can now flash jump while charging without cancelling the charge, and the fully charged attack now ignores Damage Reflect
Wind Archer's Monsoon's cooldown has been decreased to 30 seconds
Mihile's Charging Light's debuff now lasts 10 seconds and its cooldown has been decreased to 20 seconds
Aran's Polearm Booster's attack speed boost has been decreased to 2 stages (With this nerf, they might as well have to buff Blaze Wizard and Angelic Buster's weapon boosters from 1 stage to 2 stages)
Aran's Drain's recovery amount has been decreased to 1% of your Max HP
Aran's Cleaving Blows' damage boost has been decreased to 10%
Phantom's Mille Aiguilles' number of hits has been increased to 3

You can no longer equip multiple Tower of Oz rings and unequipping them will cancel their buffs

Magnus and Arkarium no longer use party death counts and instead use individual death counts

Chaos Root Abyss now has multiple channels

The Monster Collection now includes monsters from the Arcane River along with a new Cube Chair reward

Burning Fields now gain stages faster

Dodo, Lilynouch, and Lyka now spawn more frequently

what. u cant remove the balrogs :O!!!!!

Because, Monster Collection.

The Boss Arena no longer exists, although I forget which particular update removed it.

However, Zero (and every other class) should have their own emblem now. You may have to wait until level 180 to receive the quest for it.

HOM patch removed Boss Arena

I showed up after Heroes of maple or around then i think. (heroes of maple blockbuster event and leveling new hero characters events were still going on but already started when i started playing) Boss arena was still around. It was a more recent one.. very recent.

Most Recent.

The Boss Arena content has been removed and is no longer available. Characters inside will be able to use the portal to leave but they cannot enter again.

This change was implemented in the Strange Stories Patch which included changes from KMS's 13th Anniversary, but because of the "Condensed" plan that Nexon proclaimed, the Patch Notes didn't mention this change.

This patch was also when Hayato, Kanna, Jett, and Beast Tamer finally received their own class emblems.

the one that give you a ship might be more worth to removed

They already removed Rune of Barrage.
