I merged your two threads, lorrapaw. I would have thought that the saves would be compatible - other members have previously used saves for full downloaded games with no problems.
Did you find your game folder with all your saves? Did you renumber the file that was sent to you? Make sure it follows the exact same format as all the other files in the folder. If the game locates saves by date order then you may need to scroll through all your saves in the in-game load screen to find the new one.
