hl.exe - Application Error, Memory could not be read

Actually, I had admin mod before Steam came along and screwed everything up so since I didn't re-install it, I don't think it is a factor. The message about restarting doesn't seem to matter since I can train my bots and they work. However, they forget if I quit CS and come back and I have to train them all over again.

Ok, really feeling retarded here. I forgot that I renamed some folders like "exp" and "maps" when I was having problems before and I never went back to rename them. Sorry for wasting anyone's time. Thanks for the help though!! STEFAN RULES!!
