Layout designer & options no longer visible

Hi there,
Recently I added the JSN Poweradmin addon for Joomla after a friend recommended I try it. I have since decided I do not like some of the changes it made to the admin backend so I removed it. After removing it I find I no longer seem to have the designer tool/menus for the Gaming Zone template.

When I select the style to edit, I get the first tab where the name is set and nothing else. Reinstalling the template doesn't seem to have fixed the issue either.

Aside from a fresh install, is this something that can be resolved relatively easily? I am happy to provide an admin login if that would help.

We can not help you if you played with some component and now something does not work unless you pay for fix.
