My woman received MW3 from cdkeys and it labored nice until at the moment.

So my girlfriend purchased mw3 from well-known cdkeys on the eighth of November it labored immediately with no issues.

However at the moment she turned her xbox on and tried to go on the sport and now it's apparently unistalled itself when it says "set up stopped" it says her library that she owns it? So I'm confused what’s the matter? She owns mw2 as properly she purchased that from disk if I recall accurately. I don't have a xbox so I'm simply making an attempt to make sense of what's occurring im simply making an attempt to assist her.
