Hi XstreamINsanity, and welcome to the forums!
It's possible that there is a very old authorization still pending. In rare circumstances, they don't clear off completely after the 30 day window elapses. That can be fixed manually by a representative.
You have a couple of options for help besides calling. You can also email (also through the Contact Us page), or if you use Twitter, you can try @AskPayPal.
I hope this helps!
