If you do, try different computers and different usb ports. We found that only certain usb ports worked for dling program. It was very strange. I think only high speed usb ports work, but I can't confirm that.

When you are using a USB/Serial adapter the COM port assigned to the adapter will be different for each USB port.
You can look in the Windows device manager under serial/parallel ports to find the COM port # of that adapter on that USB port.
