XBox freezing after VF game update

I don´t know, if this patch is new or older, because I didn´t play VF for a while..
But when I started it today, I got a game update, confirmed, downloaded, and my XBox freezed..
I restarted, everything was fine, I logged in on LIVE (from the dashboard), my XBox freezed..
Tried this several times, everytime totally freezed!
When I didn´t logg in on LIVE, everything worked fine and I colud play any game (including VF) without problems...

Anybody had similar experiences?
I´m quite confused, how this could be fixed without downloading (which is not possible without being online) a new patch or update.
