NFS Rivals Complete Edition won't upgrade

Hey!

I seem to have a problem with NFS Rivals Complete Edition on Origin for PC. Recently became a member of Origin Access, I added the NFS Rivals Complete Edition game from the Vault into my Library. It gives me an option to "upgrade" the game, so I can get additional add-ons and bonuses.
After I click the "upgrade" button, Origin starts to load and it's just an endless cycle. It won't stop until I click "Back to Library". I've clicked on "Get it now!" in the Add-ons & Bonuses lists but that does the same thing - Origin keeps loading and loading and loading and it doesn't do anything.

I've tried logging out. I've tried closing the Origin and starting it again. I've even reinstalled the client. Nothing helps.

Any solutions? Is this a bug or something?
