It only happens for a few of my games. Everytime i try to play minecraft, rage and cod 3 it will disconnect me from xbox live. But when i return to the dashboard, everything works fine and i re-establish my connection to xbox live. I don't want to re download my profile because i have read that some people have lost their profiles and can"t recover it. I tried removing some memory from my hard drive but the problem keeps happening. I had just bought a 3 month card the other day and I'm beyond pissed that this is happening.
If there is anyone else having this problem, let me know.
