DLC content not importing after download completes

After purchasing the Angry Birds DLC through Marketplace, we tried to download the world to start a new game. The download portion of the process completes (Step 1 of 2), then the Import starts and the window closes immediately. The only error message we receive is "Download Failed: Angry Birds).

We have tried restarting Minecraft, restarting the computer, Repairing the Resetting the Minecraft App. Nothing seems to help here.
