Ok so here is the problem, so I decided to erase my HD and reinstall Leopard using the install disks that came with my MacBook Pro just so i could give my Mac a good as new feel! The Process went smoothly and came out fine with no errors and my computer actually works and runs better now! The only problem is...... When I went back to reinstall Call Of Duty 4 (Mac Edition) and update it I ran into a snag. After installing it I tried to update it using the patch that came from this link: html"http://www.apple.com/downloads/macosx/games/demos_updates/callofduty4modernwarfare.html The update didnt work i recived this error something like "The installation of Call of Duty 4 - Modern Warfare (located in /Applications/Gaming/1. Call of Duty 4 ) appears to be incomplete. Reinstalling may fix this problem." I did and I recived the same error again!!!! Before the cleaning of the HD I was able to update Call Of Duty 4 with the patch. So whats going on help !!!!!!!!!!!!!!!!!!!!!!!!
