Okay - turns out the file should never have been approved because Enchantrix-Barker has "enchantrix-barker.toc" which will never load in WoW. Since it WAS approved, however, it wasn't marked as client-compatible so it will never be seen by the client. You should give that file the correct name and re-upload, and all should be well.
The message you should have received, with a rejected file, is:
Archive is missing Enchantrix-Barker/Enchantrix-Barker.toc (name is case sensitive and must not be empty)
