Hello guys!
We are aware of those crashing issues and working really hard to fix those.
But the main crashing issue is solved by installing Python27 from this link: http://www.python.org/ftp/python/2.7.5/python-2.7.5.msi
This will solve a lot of problem regarding the crashes when starting the game.
Some other users have been experiencing some crashes after a moment in-game. We are investigating this issue and will report as soon as possible.
Thanks for your patience and for helping us out with the alpha build.
