Crash while playing. Last log message: Desync on snapshot read

I've frequently been crashing while playing. It happens more on high population servers, especially "Newbie School." I've tried all of the tips listed in the sticky post including reinstalling the game. No luck.

Are the ns2.exe symbols available anywhere? I could open the dump in a debugger and maybe find out why it crashed.
