Hmm....I have now the same problem. I have tested both with local Mac and hosted builder (all updated with latest versions) but it won't work. However, the simulator works...
Tried to install a new build of B4i-bridge but also this generates the same error to download app....
My certificates are still valid (expire later this month). Is it really necessary to revoce the keys (I still need to try it)? If yes, why? Would this happen also when developing directly with xcode with obj-c or swift?
