i need help with carbonite

With the latest release, Carbonite is one full, free addon. It's completely donation supported now due to Blizzard's recent UI Policy changes. You do not need a specific character registered to the software any longer. I would recommend updating to the newest version listed here on Wowinterface and you should be all set.
