> don't understand, can't A get his shit together with B

That's easy, B isn't communicating with A anymore. It's funded ? sure, but B has the money and has no intention to give the money back or actually create fulfill his promises.

The question is, what kind of venture is it? (between A and B). If A and B are part of the same business then he can totally be sued by backers. If that's not the case,then A isn't responsible for the money being stolen.

Is there a page or an archive of the project page available? I wanna know who created the project, A or B? it's seems like B since A has no access to the Kickstarter account.
