I guess that you bought the game right here on GOG. Read this (from FAQ):

I have paid for a game but it isn't listed on my account? What now?

There are two possible causes of this issue.If you never saw the order success screen after paying, and have received an order confirmation e-mail, then your user account may not have been refreshed properly, due to increased server load or a temporary website glitch. To fix this, follow this link: https://www.gog.com/user/refresh. This should only be required once.If you never got a payment success screen, nor an order confirmation e-mail, and you're sure that the payment went through, please contact Support. It's possible that there was some problem with the payment, and we need to process the order manually.Such cases are our #1 priority as far as Support tickets go, so we should be able to resolve ths very quickly.
