not able to start it up

[tobor]

hi guys, I've bought the game, downloaded steam, set up an account on steam

but as soon as I start steam the app crashes
steam app self updated before crashing. now crashes every time

30 minutes after buying the game I'm still not playing, quite a bad experience so far.

I'm on OSX 10.9.5 2.6GHz i7 16GB Ram

This happens to me, too. Go to your Steam Library and open US2 from there
