Trouble with testing ios app on device

My project manager added udid of my device to "iOS Provisioning Portal", I download "WWDR intermediate certificate" and "team provisioning certificate", after that I download "team pro开发者_如何学编程visioning profile" and install all that tree files. And in XCode (XCode 4) I see warning "XCode could not find a valid private-key/certificate pair for this profile in your keychain" and in Target ->Build settings->Code Signing Identity I see the same message. How can I fix it? Help me please, I'm newbie in iOS development.

See: Xcode could not find a valid private certificate/valid key-pair for this profile in your keychain
