Ok, so I went on eu maplestory and clicked the DOWNLOAD AND INSTALL WITH DOWNLOADER. It started downloading, and after a few seconds it says: DISK ERROR(Insufficient disk space). So I checked my free disk space, its over 200 GB. And so I tried the othe download, where you download the whole setup in .zip file. After a few seconds it says: "Failed - System busy". And then I was like: "F*ck me man, what am I supposed to do?". And here I am, asking you guys. Any ideas?
