Never mind I updated to 1.4 and tweaked the code all is working fine.

Hi. Just wanted to let you know that I've tested this with an Arduino Leonardo, with the RF24 library bundled with "My Sensors" (from GIT), MISO MOSI and SCK connected to ICSP as stated on the offcial Wiki: http://arduino.cc/en/Reference/SPI also works for the MEGA 2560, but you have to connect to the ICSP or use the 50-52 pins (if using it for the Ethernet gateway for example) Regards.
