I started from scratch. Attached is the sketch file I am using (basic default sketch). I got rid of the compiler warning messages (except for the memory usage) by rebooting the Pi HS3 server (which is what I am using to compile and upload the Arduino). It still is not updating the Arduino. Seems similar to the above post about pins on the WS5100 EtherShield pins, but it is not clear what you need to do to fix it. I tried to tie D4 high with a resistor to 5v, but that didn't do anything.
