Cumulus Support

I have a Davis Vanatge pro2 station and up to now have been using Weatherlink Software with USB connection from the datalogger. I decided to join the Met Office WOW network. They recommended Cumulus which I duly downloaded however I get the following error:

This error message precludes me from completing the set up

Any help would be apreciated

Thanks

You can't use the USB setting. See http://wiki.sandaysoft.com/a/FAQ#How_do ... Cumulus.3F

Thanks for the info. Much appreciated your prompt response
