I don't know

After the last mainentance I can't play 9Dragons anymore. I can play 15 mins, then my monitor is black. I can't quit the game or anything else. Ofcourse I couldn't grind at the 3x exp event, I died 5 times and lost all my good karma because of the black image and when the image is made black, the game's still running, the sound too etc. I tried to play from my notebook, the same problem. Now I'm stuck at Five Dragons 11. I missed the event. I'm angry. I wait 'till the next mainentance. After that, if I'll have the same problem... I'm afraid that I'll need to quit... AGAIN!...

Hm... Very annoying thing, indeed. You could report your issue to GamesCampus and hope them to give you some good advice, but somehow I doubt they will present you a solution... It is worth a try, though.

The first thing I would check is the graphics drivers. Are your drivers up-to-date? If they're not or if you're not sure, then I would certainly update them - Especially, as said before, the graphics drivers. If you have already the newest drivers installed, then... well... I don't know. You could try to reinstall the game, but I doubt that would do any good.

Except for the drivers, there's no good advice left, I think. Of course there are things you could try, but rather annoying than really helpful.
