Is it set for 9600, 8, N, 1?
I didn't use the supplied USB serial driver. I already had a USB-serial cable and driver for my Bearcat scanner, so when I plugged in the ODB cable it worked right away.
Try a different com port? I think the com port is the first line in obd.ini:
[OBD]
Port=Com1
Hardware=USB
RETRY=ON
