I could really use an assist on this. I was learning IOS development from a textbook. I signed up as a developer (the free one, not the $99 per year) and things were working fine for awhile, then suddenly, when I try to open my Xcode project, I get "The identity 'iPhone Developer' doesn't match any valid, non-expired certificate/private key pair in your keychains" I don't see any developer certificates in my keychain. I went to Window > Organizer, and hit Refresh, but then I get error "Too few items in teams" I don't have a clue what that means. Supposedly there is an IOS provisioning profiles page or section on the IOS developer's site, but I'll be darned if I can find it. So I'm basically dead in the water and just wondering if anyone knows how to fix this. Thanks much!
