Hi there, apologies for the problem, it was a freshly opened bundle but for some reason some of the games from it that I added myself gave me the "Duplicate Product Code" error, yet some of the others from the same bundle worked for me, so I don't get it. Anyway, I've messaged Indie Gala and I'll update you as soon as I get a reply. If they don't get back to me I'll send you another game key instead. Cheers!
