Sheetcam v8

Anyone using Sheetcam v8?

They show the new Auto Nest options, which looked very neat so I bought a license.
However, the auto nest doesn't start for me. I get a white window for three seconds
and the a message saying failed to start auto nest application.

I have sent a support request to sheetcam, no reply.
Then I read some very worrying messages on their forum that the company is sold and
the knowledgeable guy left.

Any tips for getting the auto nest to start?
