Thank you for the game, and thank you for trying to resolve the problem.

If the support ticket doesn't help, feel free to award it to someone who may have better luck redeeming it.

GOG support resolved the problem.

Thank you again for the giveaway.

Just to mention it, GOG support was quite fast. I opened the ticket on a Sunday at 20:39 GMT and got an answer and working code for Mortius1 at 9:37 GMT on Monday.
