Thanks for the ideas. Switch position was not the culprit. I am
working with Jeff at R-Track Technology to get the drivers for the USB
port. Also am going to try and download a driver for the USB-RS232
adapter I already have and have used in the past. In the mean time, I
found a computer with a RS-232 port and was able to download the
flights. So, I am good to go for now.

CH - I have also run into the memory wrapping feature that causes a
security fail. For me, it happend on a single flight. its possible
that it could happen after only 7 flights, if they were long flights
and the sample rate was high (mine is set at 4 sec.) I do not know of
a way to make the file secure and get it to pass the checks. if you
don't wipe the memory of the 302, you run the risk of losing a flight
(OLC, Badge, and possibly contest - though I'd hope they would still
score you, since it is a known problem and you can still read the
flight file.)
