I have no trouble downloading games but when I try launching them nothing happens. No errors or anything but when I checked the log i found this 

"Faled to initialize steam: FileNotFoundError("Could not find module....file name.....then it says "(or one of its dependencies). Try using the full path with constructor syntax.")  

I'm assuming this is connected to my problem but i'm not sure. Wondering if anyone else has had this problem or one similar where  you couldn't launch a game.
