Have you actually tried loading the autosave? The text name in the load screen does not matter and will be incorrect until you load the save and then manually save your game. At this point it will be the correct mission name and percentage complete.
I am having problems with the autosave, i copy over the 00 file then open game, click continue, screen goes dark for a fraction of a second, shows the same screen, i click continue again then it closes (crashes) Any tips?
