iOS Provisioning Profile Distribution "valid signing identity not found"

I’m trying to switch from iPhone development to iPhone Distribution Profile in the build.

I downloaded and dragged the iOS distribution profile into the xCode organizer.  I am getting the response

“valid signing identity not found”

Under Teams in xCode under my name and Distribution it says “No matching private key found”

I recently upgraded a new Hard Drive.

Any help is much appreciated!

It sounds like you’re missing the private key for your certificate.  Have you updated/renewed your certificate recently?

It expires June 6, 2013.   So I haven’t updated since June 6, 2012.  It gives me the option to download or revoke.  I downloaded but not sure where to drag  iOS_distribution-1.cer.    I dont see a process to update/renew the certificate.    Also  noted under Keychain Access under iPhone distribution it says “This certificate is valid”.  Thanks 4 help!
