Your screenshot seems to indicate the device is not getting detected properly.
It should display the correct addressing on boot: RX_ADDR_P0-1 = 0xf0f0f0f0d2 0xf0f0f0f0e1
I can recreate your issue by reversing the following line:
RF24 radio(49,48);
My best bet is that you just have a couple wires reversed.
