Gaming Live Disconnects when playing Cod Beta

[Mars]

I just recently downloaded the call of duty world at war beta, and upon booting the game, my 360 will disconnect from live.
When leaving it will immediately reconnect. I have tried connecting to live in the game's menu, but to no avail.
Note: I have played the beta online before I have just recently been receiving this issues.

The Call of Duty beta period expired yesterday

Sorry!

The game is coming out very soon (it's been dumped early btw) so why the need to keep the beta servers up? They took them down
