can somebody answer this for me?

[rmcguire]

Well I got APF2K8 last night...and it is an outstanding game, I get through one complete game and then try to play again a couple hours later and get his message firing up my 360:

"To play this disc, put it into a Xbox 360 console"

I had to get the "update needed to play this game" initially, but it only seems to come up on this game?

But, then this morning tried again and it worked fine? Should I try and replace this disk, or what else could be wrong?

thanks for any opinions
