Problems with game

[klvr]

Hello. I have a problem logging in to Polandmt2. The client starts normally but I can't log in. I wrote to the admin, he wanted data from the sysser file but after seeing it he says he doesn't know what it is about. Here is the data:
Exception in <module 'collections' from 'collections.pyc'> ignored
sys:1: RuntimeWarning: Cython module failed to patch module with custom type
Exception in <module 'collections' from 'collections.pyc'> ignored
0105 19:23:02095 :: Exception
0105 19:23:02095 :: in
0105 19:23:02095 :: <module 'collections' from 'collections.pyc'>
0105 19:23:02095 :: ignored
Any ideas? I installed libraries, formatted it, nothing works...
