I just got my new Davis Vantage Vue 6250, tried installing the Cpx210 ver2.exe so I can get the Cumulus software to recognize my station, but get that error file missing dll file. info says it's should install that dll file when I download that Driver, got the comm port on 1, and the baud rate at 19200 in weatherlink first, then closed it before installing Cumulus, and still get an error file, and all zeros in Cumulus, thank you all so much for your help, Ed
