I have 20 classic tbc addons, they all update fine.WoW is installed on an external hard drive.

(if applicable) Addon name, flavor (classic or retail) and version: ElvUI tbc.Please complete the following information: If I uninstall and re-install then it updates fine.

Since the release of TBC I can fresh install ElvUI (via Ajour) however whenever I try and update it I get "Failed to unpack addon).
