Call of Duty 4 Modern Warfare
Call of Duty 4 Patch Switcher
If there are any bugs please let me know. Also, it will erase your favorites (sorry I can't do anything about that. Use xfire favorites :D )
Switches between all versions of Call of Duty 4, 1.0 to 1.7. Please note: You must place the patch switcher in your Call of Duty 4 Install Path. The program will provide you instructions on where to place all the files.
