Title states the issue.

Shadow of war isn't doin nothin, cant play it through GoG, a minor issue, but one none the less that's annoying me.

I've tried to verify/repair my files but it gets frozen on "Scanning Installed files" every time.

Its getting annoying that I cant even conveniently run a game through the service, I got said game.

Anything figured out? Thanks in advanced.

That game is huge. You might have to let it scan for a really long time.
