I've been trying for a few days to solve this now. I believe that this probably isn't so much a Pilot2Atc bug as a security/permissions problem with the SQL software, but I'd like some input. So far when I try to use pilot2atc with msfs, this is the message I've been getting:
Unable to initialize database the underlying provider failed to open. a network-related or instance specific error occurred while establishing a connection to SQL server. The server was not found or was not accessible. Verify that the instance name is correct and that the SQL server is configured to allow remote connections. (provider: SQL Network interfaces, error: 50 - Local Database Runtime error occurred. Error occurred during LocalDB instance startup: SQL Server process failed to start.)
after I click okay, pilot2atc starts up but is unable to connect to msfs.
