When you open some of the older builds of Song Surgeon Version 4, you may see a message
about needing to re-register. Please try that. If it doesn't work, then here is the solution.
Close the program, uninstall it, and then download and reinstall
the last of the version 4 builds. Here is the link for that.
After doing that please open and try registering again. If this doesn't fix your problem
please complete a Help Desk Ticket
