I am not quite sure when but it _may_ be when I upgrade to Win 10 a while back. However I now get a message that I have 4 days left of my Dim Pro trial, please register. I try to register but I am told I am already registered and here is my registration code. I copy the rego code and paste in the DBox about my only having 4 days. It says "Invalid rego code. Make sure you enter the exact rego code provided by Cakewalk, which AFAIk I have done. How do I work with this, please? Thanks for
