Lightroom Classic not letting me export to NIK HDR Efex Pro
All of a sudden I am now unable to export from Lightroom Classic CC to NIK HDR Efex Pro. Using the HDR Efex Pro plugin in Photoshop works, but no in LR. The "error" I get is that after selectng and right clicking the stack of images > Export > HDR Efex Pro 2, this dialog box appears...Clicking Edit causes the "export" to fail in NIK.

In all of the years of using Lightroom exporting to HDR Efex, I've never seen this. I've reinstalled the NIK collection 3, and even upgraded to the NIK collection 4, and I still get the same dialog. I've also noticed in the "Export..." dialog box all things NIK are greyed out.

I'm stumped...any idea how to fix this?
