So my friends and I recently picked up Leviathan warships, but none of us can download/purchase the DLC from the in-game store. We're running the steam client. All we get is an error message say "Error occur while contacting the shop. 'Unknown" "Have you guys phased out the server? Is it a known bug that isn't worth your time? Is it a steam thing? Help us paradox forum, you are our only hope!
