Hey there, welcome to the forums and sorry to hear of your trouble. I posted a response on the mantis issue you were referring to: http://www.arcengames.com/mantisbt/view.php?id=7243
Pretty much same response applies here.
It strongly sounds like you have a corrupt copy of the game. Do you have the game through Steam? If so, if you can right-click the game and hit properties, then go and hit Verify Steam Cache, that will fix up any files that did not get properly downloaded via the Steam Client.
It's really hard to crash the unity engine in the fashion that you're describing, and that's the engine that the game runs on. Almost 100% of the time when you get a crash like that, it's because of the game files not having downloaded properly.
If that doesn't work, I'll need more information -- if you look in your RuntimeData folder that would be helpful if you'd post any error logs that are in there.
Beyond that, what OS are you playing on? If windows, can you post the output.log file file from in the AVWW_Data folder inside of the game's install folder?
Hope that helps!
