Jim,
We have the exact same problem on a brand new VF2SS.
We can upload to a computer without a problem. We can't download(receive) to the machine however. The machine never gets ready fo receiving. The bottom of the screen shows "Select ALL" and never changes to "Wating for Data"
I spend over 6 hours yesterday trying to make it work. I'm not sure what the problem is. It could be a software bug.
I was able to download everything else (parameters, offsets etc).I was also been able to load a proagram thru the DNS.
The problem only appears when trying to receive a single program. Also the manual says that you should be able to send ALL programs at once when the ALL is selected. Well, the machine only sends one program at a time (even thru the USB port).
It has to be a software bug.
Let me know what you find out.
I'll do the same here.
