  - Troubleshooting Guide
    - Communications Problems
    - Why can't the WeatherLink software communicate with the data logger and station?
      - Program Problems
    - The barometer graph on the Bulletin does not fill in completely.
    - No wind direction reading (or dashes instead of a reading) appears in my database.
      - Note: Since high wind speed is sampled more often, it is possible to have a high wind speed but no wind speed.
    - My archive memory is empty and I know it should not be. What can I do?
    - After successfully downloading, the data does not appear in my database. Where is it?
    - When viewing data, dashes appear in place of a value for functions other than wind direction. Why?
    - The data I want to see, such as humidity (Monitor) is missing completely or is grayed-out. Why?
