I apparently reached my maximum of authorized machines...but I don't know how. When I sold my TiBook, before I formatted it, should I have done a de-authorization? Even with that, there is my newer PowerBook and my iPod. And I've used JHymn, which supposedly authorizes itself with iTMS as another machine. I'm not sure if the iPod has to be authorized or not, but I shouldn't be maxed out yet. Does anyone know if there is there a way to check what machines I have authorized through a web interface or contacting Apple?
