Bug

kay, I downloaded Grand Chase... and the game started(i was happy) but when i tried to (or someone else) tried to start a game, I would leave the room. So I Xd out, and tried to restart Grand Chase and it wouldnt start. Then I re-downloaded it 4 times but the same thing kept happening!

I'm guessing you're using Windows Vista.

Windows Vista has an annoying security setting called User Account Control (UAC).  What you need to do is right click your shortcalled called grandchase.exe and choose "Run as administrator".  If you're experiencing any other Vista problem involving Grand Chase, visit http://www.mymmogames.net/forum/grand-chase-tech-issues/27173-common-technical-issues-possible-fixes.html#post566555 and check to see if your computer meets witht he requirements.
