Hi Alan
There is a forum specifically for Spectrum Lab that might be able to offer you more help:?
/g/SpectrumLabUsersI have used Spectrum Lab for looking at pings from Graves, or the new meteor beacon, and have run scripts which just about work, though aircraft reflections are a killer.
I can't quite see what is your problem from the error screen you attached, and am not an expert on Spectrum Lab. It's probably to do with getting sample rates all sorted out, so probably best to list your settings and send them to the above group.
