Cannot Create A New ProSites Checkout Page!

Help! I restored a server backup of my site and now I have a problem with configuring the ProSites checkout page...

Clicking Edit Checkout Page on settings does nothing... I get directed back to settings. I should also note that I trashed and permanently deleted the old checkout page so I had hoped clicking the edit page link would regenerate a new file...

I also tried deleting ProSites plugin and re-installing but that didn't fix it... (all the other settings came back after reinstall)... I suspect it could be some database issue?
