I'm trying to install NewBlue Essentials III which is quite old. I can install it but not activate it and here's why...
According to NewBlue my account with NewBlue is all in order, however they say "The issue you are experiencing is in Vegas's input window. That message (pictured below) is coming from Vegas which means they might still have the old email linked and registered with that serial. Unfortunately, I have no access to Vegas' accounts to fix that for you. I suggest you contact Vegas to get your accounts sorted out."
Apparently I purchased that particular NewBlue plugin with an old email address which I no longer use and now Vegas can't authenticate it as all my NewBlue purchases
So... where and how do I get Vegas to update or straighten that out.
