Fio with NRF24L01 - maniacbug library - not working

Does anyone have experience using the maniacbug NRF24L01 library, preferably with arduino fio?

I'm trying to use the fio to follow the steps here - Getting Started with nRF24L01+ on Arduino | maniacbug but the code doesn't seem to work - i tested this by leaving the fio disconnected from the NRF24L01, which on a uno usually just prints out the opening messages with no information about the chip. With the fio i get nothing in the serial monitor until i press t - then the program seems to start working but i never get the boot up message with all the chip info in it - is it working or not? Why is there a difference between the two boards? They are the same chip and the same connections, right?
