When you try entering the game, are you rapidly pressing enter? Doing this makes me crash.I used this installer| DragonSagaInstaller-0.1.29-20110216 | It's from the dragon saga webpage it self. I don't understand why it's like this. I just updated to Patch v.0.1.74 and it still crashes when i try to join a channel. Hope this helps.
Also, in which geographical region do you live?
