Ok, got it fixed. It seems when I restart the computer both my WeatherLink app and Weathercat lose the station config information. They were both running fine prior to the re start. So, I first needed to enter the proper start comm information by selecting the proper Usb-Usart driver and restarted Weathercat. My desktop Weathercat was then up and running. Secondly, Weathercat client indicated no IP information in the internet panel. So, I entered my ip address and it identified port 49250, so I hit connect. I then launched WeathercatRCP and it connected.
Thank you for your help. I am 78 years old, so working through the computer details takes me time.
