Ok, so please add me steam friend and we can consult for the next step.

Hello, I've attached a screenshot of what I see when I pull up the game in my purchase history. The reveal this key button is greyed out. I also forwarded this screenshot to Groupees on the ticket to see if we can get this resolved. Hopefully Groupees can help us figure this out, and if it is an error on my part I can offer another unused key for a different game if that will help.

Steam invite sent.

Hello, I've sent a few messages on Steam. Please respond when you have time so we can get this issue resolved.

Hi, the Groupees Support tell me it's a "potentially not revealed" key, so you would have already seen this key and potentially used it. Could you please add me in steam to consult? I don't want to give 1 ★ to reduce your rate directly.
