@dcr said in License Code Invalid:
What could cause the license to become invalid?
Not sure what caused this, but from the license server it seems that the license code was fine but it was missing the name and email.
Could be that the VectorStyler application data was removed from the applications folder.
Is there a file I need to backup?
No need to backup anything, just use the license key with the name and email.
Is license data stored in the application package such that I can just keep a backup of the app and restore it if needed?
Keep the original license email, that will be sufficient if the license is asked again, or if you need to move to a new computer.
