ok just now when i popped in call of booty 3 i wanted to start a new campaign so i can get the veteran achievement but when i click on Single player something pops up saying " The Version of this save game is not compatible with the current version of call of duty 3. it cannot be loaded" i know it doesnt matter because im starting a new game im just wondering what happened. Has this thing happen to any one of you? Thanks in advance.
