Some Microvellum users may get an error related to SQL server connection issues such as: "A connection to the factory database could not be established. Please select a different configuration."
Symptom: Microvellum starts up but freezes, and you're unable to click Start.
If this is your issue, be sure to close Microvellum via Task Manager before making changes to the registry.
These steps tell Microvellum to check your local database so that you can log in and reconnect to the SQL server.
Left-click on "Start Menu" and type "regedit.exe."
