Question about call of duty mw3

hi
i installed callof 2 days ago and i was playing with no problem. but yesterday when i try to open back i saw resume game option has been disabled. but on the main menu it says i already finish 17 percent of the game. and i also check save game files they seems ok. mission select option is also disabled so my only option is start a new game.
is there any way to go on where i was before.?
thank you

Try the new crack. It doesn’t have anything to do with saves but I think it might help
