Got my New PC last week with an activation code for the witcher 3. I know it hasn't been released yet so is this the reason why I can not activate the code????
Don't worry. Gog is just fine. Then you'll even get the DRM free version. so you don't need to be connected in any way in order to play it. Also, with GOG more of the money goes directly to the developers CDProjektRed. (Since they own it)
I just redeemed mine on the geforce website. You do need to download via gog.com but it's easy to sign up. Once you do that, the game is added to your gog.com account and you can download in 29 hours.........
EDIT: Just realised pre-load started a few days ago. When I get home I'm going to download it.
I got an email from PCS a few days after my laptop arrived with the activation code. When you redeem it via the geforce website, you get another code for gog.com.
