I don’t plan on using that plugin, but if it helps:
I went straight from activating the plugin on StrawDawgz.com to the settings.
Once completed, I found that links led to 404 messages. The dashboard was still accessible.
I found that the page I was using for my home page was now labeled with the names of all of your plugin’s pages in addition to its own.
I switched the database to a backup from 2 days ago and got the same results.
(So I assumed it was a cache issue at that point, but decided not to waste anymore time and changed the setting to allow complete deletion of all data.)
Deleting the plugin removed everything, including the homepage (which was the only thing that had been changed since the backup 2 days ago)
Everything is back up and linked properly and I’ve re-written the home page so I’m whole again.
