EUMETCastView set-up problem

Greetings Hugo, I have just downloaded and installed the latest version of the programme
but have encountered a problem when trying to " Download available segments from Schub / CODA"

A message stating     Assertion failed !    appears :-


Expression:! Empty0

I cannot access the programme again to check settings  and pressing  the Abort or Retry or Ignore buttons has no effect.
I suspect that I have missed a setting somewhere but not sure which. Have compared the settings on another pc and thought similar.   
Any help you can give much appreciated.          Regards,    John
