@EvgeNZEA i think that my partner must have given the game away to someone else. I know it sucks so i would like to give you two options for compensation:

1. i can offer you a new copy, i can buy the key off of another provider.
2. Seeing i would be spending another 0,85cents on this key there might be another cheap key you would prefer, you can have a look for anything under €1. If you see something else i can DM you the code.

Let me know!
