I'm currently on a vacation in northern Finland so I had to redownload MS on my laptop. I did this back in home and even managed to log in just fine although it required some auto-patching.
However, I tried logging in from here and now it seems my client is suddenly screwed up without a reason. Trying to log in through nexon.net it claims I haven't downloaded the game and trying through client says there's a maintenance on.
For some reason in Maplestory folder, most of the files have old last modification date. Even the installer is v144 for some reason and reinstalling with it gives the same old files (?) back.
