Wireless is nice, but i would go for the PIII upgrade for roughly the same price!
As for your question, I used a converter also to connect to the controller. The driver must be loaded and working before you try to connect. It should have come with the converter.
Once your computer "sees" the converter, then connect it to the controller and start the profilux software. When you try to connect, it sometimes works and other times does not... I found that everytime I started my computer, it would assign a different Com port to the converter. Therefore, you need to go to the Com port set-up within the Profilux software and have it search for it. My takes a second or two... then save the settings and re-connect on the outer screen.
If the controller does not find the converter within the Com ports, then there is something wrong on the computer side of the puzzle.
Hope that helps...
