StingingVelvet: Yeah, it's a one time activation on the DLC, same with Mass Effect 2. It's annoying backdoor DRM, but whatareyougonnado? With the Dragon Age DLC you can modify a text file to remove the need for activation, but with ME2 you can't.
Starkrun: would you be willing to part with this knowledge? im not having luck finding it on my own... if this solution works i have zero problems buying the PC pack. But i don't want to chance a wasted purchase when These methods are not confirmed or at least work with all the DLC
Search for Dragon Age here on the GOG forum, someone went into detail about it in one of the other threads. It's just an ini file you have to edit or something.
