New EA app installs demo version of game that i own full version of

I stumbled over the exact same error, i.e. I installed the EA app on my other computer (laptop for the easter holidys) and can only download the demo version of Kingdoms of Amalur: Reckoning though I own the full version and could install the full version on Origin. During my installation attempt I made a new installation path and created a new file folder to walkaround the neverending "calculating diskspace" loop.

Help, please!
