1) the "new record" and the "error" light are both flashing
Depending on what was your previous version the latest version you have installed may have additional data that would be a New Records for you, or you have actual set a new record(s). Click on the "New Record" button to see what records you have and enjoy. Click on the "Error' button to see what the error message is.
2) my weather station on Wunderground, the "active" reads "NO". and no data is displayed. Did I miss something? as I mentioned in my original post, Sorry for this "simplistic" question, as I am NOT very computer literate.
It does take a little bit of time for a new station's data to start showing up. How long has it been? If you have all the settings correct, and you can see 'Uploading Weather Underground' from the status bar at the bottom of your Cumulus main console on your computer, and still not shown on Weather Underground after a day or so then contact Weather Underground.
What is your Weather Underground station's location name?
