Problem with joining to a server

[Nixxx]

Ok, things changed a little. Now I can join the server, play for about 40 seconds and then black screen appears again. I cannot hear anything and i can't see anything, just this black screen. As I said, I've tried to reinstall NordInvasion. I also started playing cRPG and after downloading this mod (cRPG), this "blackscreen" appears every time when I play NordInvasion.
