I got the retail version of Space Engineers (Limited Edition) and put it into my computer. The instruction sheet that came with the game says that when I open the menu there should be some installation instructions. The only options that came up were "Redeem Steam Key", "Install Miner Wars", "Artwork" and "Soundtrack". I have redeemed the steam key, but there is no option to install it. Is there a way to do it from the disc, or do I have to download it?
EDIT: I have tried both ways of installing from disc (Using the "Run [Windows Function]" feature and the "Restore From Disc [Steam Function]") but both do not work. Trying to do it with "Run" just opens steam, does nothing else. But using "Restore", I cannot do it as it says there is no back-up. Is Space Engineers a game that HAS to be downloaded?
