I have HVAC Pro release 8.06 installed on my laptop (windows XP). I use the edgeport serial/USB adapter and Cable Pro 3. I can upload and download ASCs when connected to the N2 bus with HVAC Pro, however, when connected to the zone bus i get an error message along the lines of "error 1068 could not execute JCSERIAL". I can also upload/download dx's with GX9100. Do I need a newer version of HVAC Pro?
Thanks in advance.
