That's the problem. If I remember correctly, that might fall under the 'tampering' problem with the Xbox. I know there is at least one thing that seems safe in the Xbox to clean when it is in fact not.
I'm pretty sure it was along the lines of 'no liquid of any kind', meaning no cleaning agents or anything else you can think of.
In any case, if this is the original problem, then more than likely he is having problems with other games as well.
Let's hope DB comes back and reads this.
