Any help would be greatly appreciated. I'm pulling my hair out in frustration.

Thanks!
You'll need to re-image more than likely. once the UID has been lowered (and machine restarted), the change is propagated throughout the OS and it can't be restored unless you re-image the HD with the OS again and start fresh. Don't perform this mod unless you're serious about managing your administrator account.
