Trouble with the XBOX

My XBOX is very important to me, not as important as my wife and child, but its in the top 5. This week she's especially important because without Nat and Jonah, things tend to get lonely, and XBOX gives me hours of enjoyment. Lately I have been playing NBA Live '05, it’s my third season, and I still haven’t won a championship. Last night I was playing a good game, I came back from down 10 points to force OT, and with about a minute left, and my team up a few points, the thing froze up, and relayed a message that there is an error or a scratch on the CD. This isn't the first time it's happened, so I wiped of the game, and went to sleep. This evening, I was playing again, and dominating this game, I was up 20 or so in the 4th quarter and the same thing. It's really frustrating because it doesn’t save the game, so basically everything that I did, both in terms of stats and my life was wasted. I have three options; I can buy another NBA Live '05 or just keep playing and hope it doesn’t happen. My last option is the one I'm going with tonight, I'm switching to ESPN 2K5 football. I tried playing the other day, but I just wasn't into it yet. Maybe once training camps really get started it’ll feel more right, but for now I'm desperate, so I'm gonna give it a shot.
