I recently bought Gal.Civ. II as european retail version published by paradox. How do i get updates for the game. Currently i' totally lost. Clicking in Upate on the gamelauncher redirects to https://www.galciv2.com/Downloads.aspx . I have registered my cdkey with my profile and in https://store.stardock.com/myaccount/products the game and key also show up. I downloaded Stardock Central, installed it and successfully logged in. But Stardock Central doesn't shows a installed game on my pc (although GC2 v1.0 is currently running).

Clicking in "Customer in Europe" redirects my to another system, but i don't have the limited edition and my cdkey doesn't start with GC2-

Where can i download the latest patch?
