I got a strange error in my Xcode organizer when I want to update my Provisioning profiles.
Xcode says this:
Same error message here. Seems to have multiple sources. Mine was that I have a developer account and joining two teams. In one team i had no Certificates at all. In the past this did not cause any problems. In Xcode Organizer I could choose which team I try to fetch the Provisioning Profiles. And if chose the team for which I had Development Certificate the Provisioning Profiles got downloaded with no error. I think, with the new improved Member Center starting from april 2013 the Organizer fetches automatically all team accounts - without asking for a specific team. As one team had no certificate at all, the process of fetching for all teams stop with this error message.
Solution (for this problem) is to add a Development Certificate for ALL teams.
