I retried John's advice on creating a path in Magix for the plug-in with bittersweet results. First, I had to do it multiple times before it located the plug-in. That's the good news. The bad news is that it wouldn't load it. See the screenshot below. I thought that it could be a bad file since Magix did find it but couldn't use it? So I re-downloaded the NV plug-in but I got the same result? Could it be because it's the Demo version? Just guessing now.

Also, every time that I start Magix I get the "Renew the Update Service" box as seen below. What's up with that?

I emailed Magix about the plug-in problem.

Thanks again to everyone for their kind assistance!
