I am using design entry HDL v16.6 with the newest hotfix. I have been working on a schematic and the hierarchy viewer had the schematic name and the pages listed. I was trying to fix some installation and license issues and in the process I made my hierarchy disappear. Not the viewer, but its contents. I tried to go back through what I did but couldn't remember everything. Even though nothing appears in the viewer, the pages in my schematic are still there and I can scroll through them with the page up and down keys or go to page.
I have tried right clicking and choosing "show pages" but nothing happened. and I have tried closing and reopening the project.
I attached a screenshot of my present schematic and from a new schematic that displays properly.
Thank you.
Other potentially relevant info:
-I now get this error when I open the schematic "INFO(SPCOCN-245): Unknown project directive : #TEXT_EDITOR."
-I created a new project/schematic and it works correctly, no error, hierarchy is there.
