See here

Erros in downloading app

In the Designer, rename all 'back' buttons to 'btnBack' to avoid a bug in AI2. P.S. Could you export an .aia of your app (before fixing it) and try to Build it on the server ai2-test.appinventor.mit.edu ? It would be a good test of whether or not that bug has been fixed.

Change the name "back" of your components by lbBack, btBack....
