Dragon Age: Inquisition gone from my Game Library.

Are you sure you are logged into the same account? Perhaps someone else logged into their account on your computer? Or maybe you used a different ID after an Origin update made you re-enter your information?

Is it the only game that is missing, or was it the only game on the account? If you verify all these things and it is still missing, you probably have to open a ticket with customer service. I have ehard some people complaining about hacked accounts, but never games disappearing because of that. The only other thing is perhaps you were refunded? That would cause the game to disappear. Unless EA determined the code you used was stolen or fake and revoked it. Again, customer service would have to provide those answers.

In Origin, click the "My Games" tab, then underneath there's a spot where it says "Show: All Games"

Click on that and then click on "Hidden Games" and see if it's there. if it is, right click it and click "Unhide"
I've occasionally seen games end up in there (probably the result of a misclick from me)

I am 100% I am logged into the same account.

Yes, it is the only game missing, my other games are all there.

I'm sitting in queue for live chat atm so I hope I'll get some awnsers by then.

I bought my code from gamecarddirect.se , It's a swedish website with very low prices and I've shopped there before without any problems so I doubt it is stolen or fake.

The Hidden games tab is grayed out and unclickable so It is probably not there.
