I have a TC2000 device and an ENTTEC DMX USB Pro device that are connected to a computer but cannot be configured in Beyond's settings because Beyond doesn't display any ports in the COM ports lists. Device Manager shows two unused ports but they won't show up in Beyond, making it impossible to configure the devices. Perusing the Device Manager is about the extent of my computing skills. The devices were configured and working until recently. I reinstalled the drivers for both devices to no avail. It's not my computer so I don't know what caused the problem and I'm not sure whether or not the computer's user is responsible (by clicking around where they shouldn't be clicking, etc.). To my knowledge, the user hasn't updated Beyond. Could a Windows update cause this? This is the first time I've seen this kind of problem.
