I turned my xbox off by the button instead of powering down with linux. I now get this message when I login. Your session only lasted less than 10 seconds. If you have not logged out yourself this could mean there is some installation problem or that you may be out of diskspace. Try logging in with one of the failsafe sessions to see if you can fix this problem.
Ok I will do this next time. No one was responding on the forums so I just did a reinstall. Hopefully I will not accidently turn it offf improperly again.
