To check all database I have for OpenUtilities Substation

Hello everyone,

I'm wondering if there's a place or an app where I can check all the databases I created for Substation?

For example, I was working with the database SubstationCE3 (figure below), it's my 3rd database. Is it possible for me to see the past databases?

Also, I'm having a problem with it. For no reason, when I'm opening Substation it is showing me the "Configure Database" screen. If I click ok, the message below is shown:

Which translated to English means: 

"Configuration not saved: Network or instance-specific error connecting to SQL Server. The server was not found or was not reachable. Check that the instance name is correct and that SQL Server is configured to allow remote connections."

I can't open Substation because of this problem. I also tried to update this database (from "New Database" area) but it's showing a similar problem.

Thank you!
