Sparkfun RFM22 Wireless

[salama]

I have been trying to use Sparkfun RFM22 Wireless radio moduless to control my 2 wheel robot with joystick on another end. I have used now like 4 hours trying to find instructions for idiot how to actually use it. I soldered everything on and put the shield top of the arduino. But when I try to use the sample code  from RF22 library, the initialization fails.

One thing I started wonder how is the arduino able to write to the shield micro controller or does it have code already inside it. Or should I actually put the sample code on the controller on the shield. I am really confused what I am doing wrong and how I can be this stupid 

People say that using this should be really easy
