My suggestion would be to unplug everything and power down the console. Then plug everything back in and see if that fixes your problem. Also you should compare the date and time on the computer and the console, make sure they match. One last thing to try before contacting Davis is look to see if there is any downloaded records, there might be a bad one with a date way in the future or something. If there is, delete that record and see if your station downloads. If it still does not work contact Davis, you might have a bad datalogger.
