You get this error when attempting to set security settings in the Property Sheet:
Unreachable Roles Table
It is not possible to edit your security settings because your Roles table is currently unreachable. Unable to connect to XXX database on YYY. Error: Unable to connect to database.
Please make sure your database is running and your database account is still valid. Also, the Microsoft SQL Server name could either be XXX or XXX\[instance name].
This can occur when the Roles table is deleted from the current database or you change the database / server connection in Web.config and that connection is not refreshed in Iron Speed Designer.
Reconnect your database using appropriate settings in your application’s Web.config file.
