I downloaded the PTS and the Elder Scrolls Folder was not created in the Documents section. As such there is not a section for addons.
I made a copy of the Live folder and renamed Live as PTS. This did not solve the issue. I have also attempted repair, uninstalled and reinstalled and also restarted the PC between attempts.
Any suggestions?
