Yes. Did all that. However …
After several minutes on the phone with Adobe support, the guy asked if there was a change in our network at the office. There has been. He asked me to create a new root user account and log in to that account and open PP. I did that and, lo and behold, there were my effects. Not having full understanding of what the fellow was saying, what I gathered is that somehow my program is looking for things on the cloud server, even though we purchased the full suite directly from Adobe. I now have to get full admin rights to my user name and my machine in order to make it work.
Weird.
