So i bought the witcher 2 premium edition, installed it all went fine till i tried to activate it, i typed in my activation code and pressed ok, it went on and downloaded the enhanced edition, i installed that aswell, i went on to play it, it went well till i got to chapter 1 in flotsam it would work for an hour and then it would start to lagg, like 1 fps, i think it might be a memory leak, but it would go away after exiting to the menu and reloading it, but to me it seems like the drm-securom is still active, cuz afterwards in chapter 2 the same lagg appeared after zyvik took me for a tour, only now it cant be fixed by reloading a save game, it laggs in the area of the arena and if i get close to the elven prisoner, again 1 fps and less, i must add before i played the retail copy i downloaded a pirated version of the witcher 2, so i think my pc might think that this one is pirated aswell, cuz the activation screen would go ahead and download the EE even if i didnt type in anything at all...

Please help, and thanks in advance.
