View Listings – Sorry page doesn't exist.

I have tried all of these methods to fix the permalink issue.
1) Go to Settings -> Permalinks and click “Save Changes”
2) Go to Real Estate -> Settings -> General (on version 2.7.9), verify the Listing Page setting is set to the correct page and then click “Update”
3) Update the Listing page in the Pages -> All Pages section.
and this
These usually work however there have been a couple sites that this did not work. Check to see you don’t have any pages called “Listings” in your Page Trash or any other real estate plugins installed.
and I still get this“Sorry The page or document you are looking for doesn’t seem to exist.”

I have tried it with other themes and turned off all plugins. I have uninstalled and reinstalled the plugin. Not sure what else I can do.

I have submitted at least five support tickets regarding this and have heard nothing back.

I am going to continue to post this problem until someone responds to my requests or refunds my money.
