Good afternoon. People on these boards have saved my bacon more than once. Had an old VP that has been giving me fits for three months. I finally broke down and bought a VP2. Everything went well until I hooked up my existing WeatherLink Data logger, and now I get said message. I have tried to unplug power down, wait ten seconds replug the logger and put the batteries back in and still get the same message. I should also mention it is a serial logger and 6.0.2 WeatherLink, and I can't find the install CD for the past 4 or 5 years.
