Plug-ins for BusyContacts and DevonThink not working

With the recent up-date to Busy Contacts, I was finally able to again see my correspondence with various contacts in the sidebar. It is not working any more and I am sad.
I’ve had issues with the DevonThink plug-in since using DT and haven’t had time to resolve.
Any ideas?

User error. Apparently my security preferences had reverted to App Store only. . .Fixed now.
