If that doesn't fix it, you can try running it during a clean boot:

Booting clean in Windows XP:
1. Click Start --> Run --> Type msconfig --> Click OK
2. On the General tab, choose Selective Startup
3. Uncheck Process SYSTEM.INI file
4. Uncheck Process WIN.INI file
5. Uncheck Load Startup Items
6. Click on the Services tab
7. At the bottom, check Hide All Microsoft Services
8. Click Disable All
9. If running the game on Steam, re-check the "Steam Client Service"
10. Click OK
11. Click Restart
12. After reboot, run the game to see if it works.

After performing the necessary steps, restore your settings by doing the following:

1. Click Start --> Run --> Type msconfig--> Click OK
2. On the General tab, choose Normal Startup
3. Click OK
4. Click YES, when asked to restart your computer
