Just make sure that you have the Twitch client set to update Carbonite with alpha's. Ircdirk pushed a alpha release yesterday to solve some of the errors.
In my defense - I must tell you that I haven't been able to play WoW for three years (computer got burned out and I haven't been able to afford to replace it). I do, however, try to keep up with changes to the game. And I recently found out that I can update some of the addons that I did (everything except any of the addons that I have to make graphics for). I am "stuck" with having to use an Android tablet (Acer).
EDIT: Oh, while I think of it, try with ALL of your other addons (except Carbonite) shut off. There could be a conflict between Carbonite and another addon, and doing this is the best way to tell. \EDIT
