The game opens but it doesn't show it on Steam. When I open the game, it doesn't show it in the game but shows it directly online.

Hi! There is an unfortunate formatting error when installing Ship Simulator Extremes and it asks for CD keys. It is not obvious what CD key is requested. The installation will ask you for the CD keys of all DLC's you purchased, and usually it starts with the latest DLC. So if you get the "invalid CD key" message. Try the other CD keys (start from the bottom working your way up). Hopefully we should be able to resolve the formatting error so that the problem will go away. Apologies for the inconvenience...
