Cannot use "Edit in" on my LrC, with Ps and my Topaz apps all grey

I have just upgraded my Topaz Photo AI app on my MacBook Pro, and now find that I cannot use the "Edit in" button in LrC, with all of the possibilities listed in grey.  I cannot see how the installation of the new Topaz app  could affect my access to Ps, even if it prevented me from accessing Denoise, gigapixel, and sharpen.  Can anyone help, please?
