Looks like an invalid certificate/keypair.
At this point I would start over from scratch. This would involve revoking your Apple iOS Distribution Certificate on the apple developer portal.
Make a new app.
Give it a AppID, create the AppID on apple developer portal.
Follow the PDF walkthroughs that we provide on the iOS Certs tab to create a iOS Distribution Cert.
Next create a provisioning profile associated with the distribution cert you previously created (you should only have one since you revoked the previous ones you created). Download it and copy it to the www folder of your project. Then in project settings, pic the ad hoc provisioning profile.
Then build (uploading when prompted).
If all else fails, try the steps above with a new account. If that still fails, let me know.
