Problems with first mission XB360 version

[sbeirs]

I got this for Xmas from my brother along with the ace combat stick and throttle.

I have not been able to complete the first mission of the BOB campaign as it locks up at various points during the mission, but I have not been able to shoot down the first two HE-111's yet. I have been able to complete the first 3 or 4 tutorials with nor problem.

also the MP server seems to have been down all day today any one else having problems with that as well?
