Before we can ever help you on your problem, we need more information about your "crash".
Since you are on windows, the only way I know to trace/output infos on game runtime is to launch Western Quake 3 with the additional "+set logfile 2" in your "quake3.exe +set fs_game" command line ...
Hope you understand what I mean.
If you manage to do so, a new log file called qconsole.log should appear in your "westernq3" folder.
If so, you can post its content, and we may help you, further.
