Hmm, I need some help please guys.
A couple of days ago I installed a 360 version of 'Portal' that has now become backwards compatible. I had originally purchased this as an 'Arcade' game (i.e. digital download, so no physical disc).
I played this a couple of times a few days ago, but now cannot find it anywhere! It doesn't appear in 'My Games', and it's dropped off my 'recent app' activity on the home screen.
As I don't have (or need) a physical disc to play, how on earth am I supposed to play it?
The help pages are very vague about this, and I'm stumped.
*edit*
And as if by magic, all my 360 games now appear on my 'Games' list. Why did that happen?!
