When using Update Server, if you receive Run Time Error 10048, this indicates the program is unable to open the specified PORT to communicate with the computers running Assessment Writer.

Check if there is another instance of Update Server already running and listening.

Check if there are any other programs using the port specified in Update Server.

If you are unable to find the conflicting program, under FILE -> OPTIONS choose a different port number and update the computers using Assessment Writer to use the new port.
