@Former user, thank you for the detailed video. I had already done that. SFP is working fine in VP14 and 15. It's 16 where I get the error message when I select it from Scripting.
I copied over the VP14 folder again, and still the same error message. If I start SFP first, I do not see the error message, but I can not "Send" anything to the timeline from within SFP.
I'll do a complete uninstall/reinstall and see what happens. I just updated to 352 from 307 where SFP didn't work there either.
