Hi.

I have been given my GOG key (via Humble Bundle), but for some reason or other GOG will not accept the code.

What I mean is, I logged into my GOG account, and selected the link from Humble Bundle. I entered the code that was given, and Grim Dawn Pioneer Edition shows up in the list (not in my account, just shows for the key), I press Continue, and GOG gives me an error asking me to refresh the page, and try again.

Yes, I was logged into my GOG account before activating the code (at least tried too).

Not sure what is going on here, can anyone help me?

I own the Pioneer Edition of the game which I purchased from Grim Dawns Website.

Note: I also tried using Chrome, and Firefox Webrowers if that makes any difference.

Well, if the game did not get added to your account and if the code is now not working anymore / does not let you redeem, you should contact support about it since they are the ones who can help you:

Thanks for the reply. I got everything worked out.

cheers, and take care. :)
