Hello hpr3,
Congratulations on your new Apple TV! Also, thank you for the details of the issue you are experiencing with Crackle on your Apple TV. I have a few suggestions to resolve this issue.
First, I recommend reviewing the steps in the section titled "If you have activation issues with a content provider" in this article:

If you continue to experience the issue, I recommend restarting your Apple TV:
Restarting your Apple TV (2nd or 3rd generation) using the onscreen menu
If you have Apple TV software 5.0 or later installed, you can restart your Apple TV using the onscreen menu. To restart your Apple TV chooseSettings>General > Restart.

If the issue persists, I recommend restoring your Apple TV:
Restoring your Apple TV (2nd and 3rd generation) to factory settings
On Apple TV, choose Settings > General > Reset, and then click Restore.
Your Apple TV will restore to its factory settings, and will also download and install the latest Apple TV software update. This process may take some time. Do not disconnect your Apple TV's power cable during the restore process.
