Hi jarrett1fan,
Sorry to bring bad news but the save game is probably lost.
Save games usually need some other files backed up which aren't necessarily in the save folder (data files etc.) Make sure you are putting the save file in the right folder. If you are then other files would be the problem. In future when backing up a save file, try going to find file and search in the main game folder (including sub-folders) for files modified at the same time and copy them aswell, making note of their respective folders. Try it on a practice run now to see if it works.
