Dim Pro won't accept correct reg code
I have an existing installation of SONAR and Dim Pro on a Windows 10 laptop. I hadn't started SONAR on this machine since Gibson pulled the plug. I'm finding that the Dim Pro instances are silent and are wanting the reg code. When I put in the correct reg code I get...
Error
Invalid registration code. Please make sure to enter the product registration code exactly as you received it from Cakewalk.
I've tried entering by cut and paste and typing it directly. Is there a work around?
I've collected a number of Dim Pro serial numbers and reg codes over the years. Should I try those?
