Having just gone through this myself, I highly recommend you contact Apple Developer Program Support and have them walk you through the process of resetting your certificates and profiles. It is not a difficult thing to do manually, but there are lots of ways to muck it up (I speak from experience) AND the more people that call the more likely they are to continue improving the process.

That said, the short(-ish) answer is to delete all of your developer and installer certificates from Keychain, then delete all certificates and provisioning profiles from the portal, then create them all again from scratch, and then refresh Xcode to bring them all in.

Oh, and be sure to back it all up when you're done!
