Packaging Operation Failed in Xcode 4

When I use Xcode 4 to create an app IPA fie, I go to Product --> Archive to get an Xcode Archive. I recently read the SO post here detailing on how to distribute an app in the AppStore. I followed the instructions in this post and my errors still persist.

First, I begin with validation. When I click Validate I login, elect the correct code signing ID and then get the following error:

I get the same error message when I attempt to distribute to the AppStore.

Any ideas as to why I cannot share and/or distribute my app?

EDIT

Previously, I was having trouble validating and distributing and as a result I would receive this error:

I fixed this problem by finishing my CCATs / Encryption Registration in iTunes Connect.

I got the same error and found this solution (Xcode 4.4).

In Build Settings/Code Signing I had "Don't Code Sign" in my first Archive attempt.

I then put a valid Distribution Certificate (in the Release identity) and, after Archiving, validation of package went flawless.

Thanks to Apple that at every release does something (undocumented) different from the previous version.

Cheers.
