Crash upon opening

[Urkle]

I am fairly new to steam and decided that Penumbra would be my first purchase. I have played a few other free games and demos which worked fine but I cannot get any of the 3 games to open to save my life. I imagine it is probably something simple or stupid but I have spent the last 2 hours searching with no luck. Here is the error code I get. I played amnesia fine yesterday but today not even that will work and I assume it has something to do with 10.9.2 but I don't know what I should do from here!

Ugh.. yes.. Apple can't make up their mind on that one.. To crash or not to crash.. everything RAN in 10.9.1. There are updates versions coming real soon that'll fix thing up on 10.9.x correctly..
