Every time I try to join someone's game[Gameranger or Westwood], after I create my character I got a message "Your Nox installation is corrupt.". Reinstalling game don't help.
Maybe You can help?

Yeah, something is wrong with your installation/registry enties. Are you sure you installed with administrator privileges?

Yes, I'm sure.
My friend have the same problem.

Have you tried the Noxforum installer?

It works... That's strange, I have to use illegal version to play online, lol.

...But now I got other problem - corrupted graphic :P
