I've been getting the "not well formed (invalid token) at line 1 of last-saved_game.xml" error as well. Went in and deleted cache and settings folders. Didn't work. De-fragged hard drive, ran anti-virus, nothing works. I've noticed that in my Documents folder, it's been creating a new folder for Sports Interactive each time I start the game (so I always have 2), keep deleting the empty one to no avail. Could the extra folder have something to do with it? Didn't have problems until the new patch.
