I have a problem starting a game.
You see, I try to start a new game since I'm new and I get the following error.

ASSERT FAILED!

C: / program files / bots / about.dat
File: f: boutÁÜ% / Ona / source / engine / cmapmanager.ccp
Line: 855

Expression: 0

I have no idea if it's a problem with the client.
or is the fact that I have windows 7 and this game is for XP
