I tried a few of the suggestions but no luck, it was Friday the 13th.
Tommorrow I will try doing it with the PC but I think it is some kind
of lapse in the 302. I had a nice flight and I will be happy with
that.

I had exactly the same problem yesterday during the contest in Uvalde.
In my case, the download would stop after 57 blocks out of 227.
Luckily there were people on the site that knew what to do. I needed
to upgrade the 302 to the latest firmware available from
www.cambridge-aero.com. That fixed the problem. The upgrade utility
for iPaq did not work for me, so I had to do the upgrade from my
laptop through a serial cable.
