Reznov64: I am missing Spec Ops: The Line, Turok Escape from Lost Valley, Adventure Park, Unreal Tournament 3 and JYDGE.
This isn't answering where the bust is. I have it, see attached.
1. As Zadette said, use this first and see if the games are there:
https://www.gog.com/user/refresh 2. Wait for a response from GOG Support. They'll take a while, but they'll get back to you and restore your purchases to your account - if they were legitimately bought.
3. Don't use any grey key sites for many reasons cited above by others. Buy it on other platforms instead if available. e.g., Steam, Epic, itch, etc.
4. If #3 cannot be done, go you-know-what instead of buying fraudulent keys and potentially funding crime, hurting devpubs, and risking wasting your money if it turned out to be bought with a stolen CC.
