First try opening your game center up and logining in- the problem is the program automatically tries to reach ur gamecenter if you do not have it running it will bug out and crash or not open.
Second open up steam (althought this should not be the problem)
If either of those don’t work don’t blame the developers and coders for their hard work, it’s probs just your comp being just a lazy as you :)
