you need to change your com ports. Once you have changed them to com 1 and com 2, then delete the modem and port. Re-Install, then redo your ports.
The reason for this is that you need to free up com1 and 2 before QXDM or other programs can read on them. Why... Well, its Microsoft for ya... Ya don't like it, go to Unix :buddies:
Any who, once you free up the ports, then put the modem and port back on Com1 and 2, you should be fine
