I am on Windows and whenever I try to open it nothing happens. I've read other people have a loading screen error due to having saves from the demo but that shouldn't be a problem for me. It also doesn't match the description. I click it, it does the little loading circle instead of the cursor for about a second, and then nothing happens.  If you know what's wrong any help would be appreciated.

I found a solution although this is probably just my computer having problems rather than the game. If you add the game to Steam and run it through Steam it works fine.

same prob
