I got it working! (win 7 64 bit)

A lot of people post about getting the openal32.dll from the Creative website to fix the sound issues. It seems to be down at the moment. However, you can get it from blendo: http://www.blendogames.com/dev/ grab the oalinst.zip, extract, install.
Also, if that doesn't solve all your problems, grab the kn-atigktxx-10.4.zip and place the extracted dll in C:\Program Files (x86)\Steam\steamapps\common\airforte\data

Tried both options and It's still not working for me... it keeps freezing the screen when I move my mouse... T_T..

I can never get this game to work..

Hey thanks this worked for me. Now the game no longer crashes and I get sound. Then, thanks to another user here on the forum, I went into the game folder and copied steamwrapper.dll into the same folder, then renamed the copy to steamwrap2.dll and now achievements are working too.
