Ok, I did get the RIO Receiver working, abet temporarily. The problem was that I had the second Address not set the same as the first. It worked great. When I turn the unit off the ARM software cannot connect to the Rio again...

Setup:
Rio Receiver connected through a crossover cable to a NIC:

ARM settings:
First address: 192.168.0.2
Second address: 192.168.0.2
Network Mask: 255.255.255.0
Player IP address: 192.168.0.26 (changes each reboot)

NIC settings:
IP address: 192.168.0.1
Subnet Mask: 255.255.255.0
Gateway: blank

This thing is about to become a RIO Paperweight or a RIO Frisbee...
