Missing device from Ad Hoc Profile selection

I have a really odd issue where one particular device will not show up on the "Generate Provisioning Profile" screen of the Apple Developer Account. This is the only device that is missing. I have added 9 others successfully. I have tried/checked the following:


1. The device is definately registered and enabled

2. The UDID is correct

3. Logout / Login of the Apple Developer Account

4. I am definately under the 100 device limit with only 9 devices

5. I created a new provisioning profile (still missing)


I cannot think of anything else to try. I would appreciate any help.


Thanks,

Wade
