Is WeatherLink getting any data from your VP2?
Which datalogger do you have?
If it’s the USB version, when you ran WeatherLink to find the COM port, did you tell WeatherLink that you had a Serial or USB datalogger?
If you set USB then the datalogger is working in USBexpress and WD won’t pick anything up from it. If this is the case then have a look at this FAQ.
