As the server was laggy and the login queue was activated yesterday (at least on EU) it might be the ZOs disable it again for addons to less-stress the servers.
If it works for others though it's unlikely they only did disable it "for you"
Maybe wait a few more days.
And about TTC:
Check the description of the addon please, it should be written there what it is able to do and what not.
Or have a look at ATT as well
