Somebody please help. I've been tearing my hair out over this problem for 3 days now. I've been working on a new app, and everything was going fine until Wednesday of this week. I had built the app for testing on my device a few times, and thing were working ok, until all of a sudden I got the "Application failed codesign verification. The signature was invalid" message.

I've deleted all my keys, certificates, provisioning profiles and my corresponding info in the Provisioning Portal, and I've resubmitted a certificate, made new profiles and installed them but still get the error.
My app will install onto my iPhone, but, with errors. I have a menu in my game with 6 options. Two of the options return a "Director Class - Error. Director Error. Failed to load module 'letters'. " message. The app works fine in the simulator.

Any ideas?

Thanks
