I just wonder if this is a known issue with Air 30. I have no problem to install my game with ad-hoc provisioning profile, but when switched to develop certificate and provisioning profile, I got that APInternalError again...
I did see the post on adobe forum and an error tracker... but as I don't see ppl on this forum talking much about this, I started wonder if this is simply my own problem.
