Hi there,
I overheard that the whole support team is on your case ;) I'm sure that Firek and guys will get your case resolved as soon as possible.

Yeah, it's just a misunderstanding and I apologize for the confusion. We don't claim that you never purchased the game, however it might have been purchased on a different GOG account. Things like this happen more often than you might think.

Of course it is possible (however unlikely) that the game disappeared from your account somehow, but we need to make sure that there isn't a different reason, before we ask our devs to spend aeons combing our system in search of a bug that may not exist.

I don't want to go into too much details on a public forum - please respond to my colleagues' last message at your convenience and we'll resolve this ASAP.
