When I start SIGMA, I get the following alert: "Database open failed." and "There appears to be a problem with the database. Please try again."

A database open failed message indicates that SIGMA is not able to connect to the local database.

SIGMA 1.0 version is using Microsoft SQL Server 2005 Express. Please check the following:

  1. Select Start ->Run, then type “services.msc” and click OK
  2. In the services dialog, please check if you have the following service on the list:
    SQL Server (TRANSOFT)
  3. If you do have that service, please make sure that it is started. If it is not started, please right click on it and select Start.
  4. If you do not have that service on the list, or you are having problems starting it, please contact our Technical Support.
