My lady acquired MW3 from cdkeys and it labored high-quality until in the present day.

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

However in the present day 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 nicely she purchased that from disk if I recall appropriately. I don't have a xbox so I'm simply attempting to make sense of what's taking place im simply attempting to assist her.
