Have you tried removing the printer from within control panel and then restarting to let the system find the printer? Does the port show up in device manager? Have you tried to remove it from device manager and restarted the pc? I am not sure what the properties box looks like within ME but on xp you can tick the port you wish to use. Is the computer stand alone or is it in a network? If in a network is the machine the gateway pc or do you use a router. Sorry there are so many questions but this is information that you should have given.
