Edit in WaveLab is grayed out

I have an audio file selected, and “Audio/Edit in Wavelab” is grayed out. How do I fix this ?

The first and most obvious question would be, do you have Wavelab installed and activated?

Yes, I have WL installed and activated. What’s strange is that only a few others over the last 7 years have had this problem, but noone seems to have an answer.

Sorry. Here are my specs:

Cubase 10 and Wavelab 9.5. It has worked before. I can’t for the life of me figure out why this doesn’t work. Regular work takes time, but problems like this are just a time killer. No 2 ways about it. Getting really fed up.
