I recently had my xbox repaired (red ring of death). When I hooked it back up, I was prompted to re-register and was given a new login name--MainSnailXXXXX. Since then I have been unable to access games already saved on the hard drive when I used the old login name--TitteringStormXXXX. My son likes to play Skylanders, but now we are prompted to start all over instead of being able to pick up where we left off. I also am unable to access the Points I bought as TitteringStorm. What can I do?
