Any divers out there? I have a Citizen Promaster dive watch records data while you are diveing and then connects to you PC to download the info. I have Win XP and all the connections but the program asks for the "serial port" and I am connecting it to the USB and it doesn't want to download anything it says incomplete? I know it is recognised because when I remove it from the computer it gives off a sound but I just can't download the info!!! Anybody any idea what the problem may be?
