Hi. I bought the Ultimate RED Collection directly from GOG, and all the gift codes return:

"Something went wrong. We are very, very confused. Please try again. If the problem persists please let us know."

Already made a ticket about it, but it is a real bummer to gift someone just to leave them hanging there with failed expectation. Someone else with this problem?

Are you gifting to somebody in a different region?

Hmm, not at all, we are both from Brazil. Well, my friends account was created today to redeem the codes, she didn't have a GOG account before.

One of the codes was redeemed correctly right now, but the remaining two still are a no go... hmm... pretty strange.

Have they tried a different browser? Redeeming on non chrome / firefox has been an issue in the past - though sometimes I've had that message pop up (both here and on steam) and the games redeemed anyway.

Now we tried in another PC, and in the other one we were able to redeem all games, but the discount codes still give the same error. Only when removing the discount codes the error disappeared.

Well, all things considered still a good deal, and who knows, maybe support will still help into redeeming the extra stuff!

I'm sure if you still ned help support will do everything they can to help you. The GOG support staff is absolutely fantastic. The two representatives I've had the privilege to talk to (Falran, and Ponczo) were just wonderful people, and extremely helpful and supportive with helping get my issues taken care of.
