I put my profile on another xbox 360 in my house and I can access it . It gives me a message that says something like please reinstall game and returns me to home menu every time I try to recover my profile. This problem is very strange to the fact that we have had our xbox 360 for four years with out a single problem. There should be no problem with the hardware because we take good care of our stuff. Could someone please tell me what is wrong and how to fix the problem.
