RF24 Library and Leonardo problem

Hello :) I'm having a problem getting the getting started sketch from the RF24 library working with my leonardo. according to this http://bit.ly/1cTUBmd (google groups) all i need to do is connect pins 5, 6, and 7 from the radio to the ICSP headers on my leonardo and make a few small changes in the code.

Adding this line:

 while (!Serial) {}

after this:


and changing this:

 RF24 radio(9,10);

to this:

 RF24 radio(8,10);

After that all i get is a blank serial monitor instead of the debug message that i am supposed to get [Tested and working on Arduino Uno]

Thanks in advance for your help :D
