[@Dave Hovey] Hello Dave,
This license key you are having is for registering the Home edition of Genie Backup Manager 9.0 (GBM 9.0). So, are you sure you installed the Home edition, not the Pro or the Server one?
You may uninstall GBM without keeping its settings, then download the latest setup file of GBM Home 9.0 using the following link: http://downloads.genie9.com/gbm/GenieBackupManagerHomev9DR.exe
Run the downloaded setup file and proceed with installing GBM.
Can you register it using your license key now? If not yet, please feel free to contact the support using the following page: https://www.genie9.com/Support/ContactSupport.aspx
