I hear ya, will be waiting on an answer to this too. Autodance was my fave app until the update. Now I can't share, use the community or even login without it freezing and booting me out The developer hasn't answered any emails. Frustrating! Just want to share one vid to Facebook. Tried restarting the app and my iPhone 4S numerous times even going into the app everyday to see if its fixed yet, further wasting my time. Could they not leave well enough alone?? Sorry for the vent but I am finding it is common problem for many and its just not good enough.
I found this article that might indicate that the Autodance app in any incarnation is currently being retooled and isn't currently available: http://www.technologytell.com/apple/107909/you-can-autodance-if-you-want-to/
