ok there's been an update to Origin tonight as well as an update to nVidia drivers (both the same night) and now the game works. Dunno which update corrected it but now it's working.
The problem seems to be with the ActivationUI.exe program inside the Core folder. The version of this file is 4.6.1. The other Origin games i have installed that are working (Dead Space and Crysis) are using the 4.2.4 version of this (DRM?) program. If i try to replace the 4.6.1 version Dragon age Origins is using by the 4.2.4 version Crysis and Dead Space are using the game doesn't launch but the error is different. It says my game is not well configured and i need to re-install which is normal cause i'm not using the correct version of ActivationUI.exe for this game.
So i don't think the problem is with the game at all. The problem seems to be with ActivationUI.exe 4.6.1.
Using a simple google serach i can see i'm not alone to have problem with ActivationUI.exe. Lot of people do under different games. The dll file listed is different but i guess it's the same problem.
Anyway know how to solve this without re-installing windows? Cause i'm certainly not re-installing windows.
