I discovered something that works spectacular for me, but not sure if it is the overall issue here. It appears that on ALL of my gaming PC's in my house has the same issue because of running the Nexon Launcher and/or Game client on the SOLID STATE DRIVE (SSD). I decided to delete everything maple AND Nexon Launcher from the entire PC (again f3), but this time I manually redirected ALL installation folders to install both the Nexon Launcher AND Maplestory client to my Standard Storage Hard Disk Drive (HDD). This seems to have immediately corrected my issue and now the Maplestory Client runs absolutely PERFECT with no stability issues. This would explain why our Gaming Laptop was the only one that could play this game because it is our only PC that does NOT have A Solid State Drive (SSD). I hope this actually helps at least some players, if not all, who are having this issue. It may possibly be an issue with the speed transfer rates of SSD's that the Nexon software is not yet updated to handle?
Yea, before the unscheduled maintenance was the best few days of an incredibly stable server connection I've ever had in my 8 years of this game. I was blown away by how the impossible was achieved. Then came the unschedule maintenance and bam, game destroyed again.
