Did you update my server software to the latest version since we last spoke?

On the login/logout screen, when you browse your server directly, you will see the version of the server software at the bottom of the screen, e.g. PNPSCADA 1.120213113309
This version number is actually the build date and time, in the format 1.YYMMDDhhmmss.
On account of the glass wall, the easiest way to ensure you're looking at the right server, log in, make sure it is your server based on the Overview screen, and then log out, and look at the version number on the logout screen.
