IAmSinistar: First off, yes, I have contacted Support about this issue. This thread is just to see if I'm alone in this struggle.
So, I was doing a trade and the recipient said that the GOG code I sent was coming up as an Invalid Code. I had the member try another I had bought for the same game, and that failed as well. So I tried yet another key myself, and that too came up as Invalid.
Guess what? A dozen keys, all purchased since GOG rolled out the new design and from the Last Chance sale, are Invalid. Superb, eh?
I noticed that the keys looked different after the new site design (they had a single trailing character after a hyphen), and today they went back to the more usual format. I'm guessing whatever changed the formatting didn't get fully implemented, so the patterns don't match somewhere down the line.
I hope I'm alone in this, and that GOG is working to resolve it. But if you've been bitten by this too, please share your experience.
had the same problem this day, the code in your gift shelf (xxxx-xxxx-xxxx-xxxx) is wrong, probably a bug. this applies to all gift codes bought recent (guess one week). just look at the email certificate, there will be the working gift code (xxxxx-xxxxx-xxxxx-xxxxx).
amund: My gift codes from the Last Chance are invaild, older ones work fine. I hope they fix it soon.
