user27719: I am trying to connect my Arduino Pro Mini 3.3V to an nRF24L01 transceiver and cannot see what I am doing wrong. I've checked my wiring a million times because the problem hints there is an invalid or no connection between the Arduino and the transceiver. I have the following pin connections:

Arduino --------------- nRF24L01
--GND ------------------- GND
--VCC ------------------- VCC
---D9 --------------------- CE
--D10 -------------------- CSN
--D13 -------------------- SCK
--D11 -------------------- MOSI
--D12 -------------------- MISO

I am using the following sketch
#include <SPI.h>
#include "nRF24L01.h"
#include "RF24.h"
#include "printf.h"

RF24 radio(9, 10);

const uint64_t pipes[2] = { 0xF0F0F0F0E1LL, 0xF0F0F0F0C2LL };     //Addresses to send/receive

void setup()
{
  printf_begin();
  Serial.begin(9600);
  radio.begin();
  radio.setRetries(15, 15);
  radio.openReadingPipe(1, pipes[0]);
  radio.printDetails();
  radio.stopListening();
}

void loop()
{
  const char text[] = "Hello World";
  radio.write(&text, sizeof(text));

  delay(1000);
}

I have no clue where I am going wrong. This setup works well on my Uno, however I cannot replicate it on the Arduino Pro Mini. Can anyone tell me if I am doing something super wrong that would prevent this from working? I'm all out of ideas. Appreciate any help in advanced!
Update: 
I forgot to copy and paste the output from printDetails(): 
STATUS  = 0x00 
RX_DR=0 
TX_DS=0 
MAX_RT=0 
RX_P_NO=0 
TX_FULL=0

user19867: Whenever you get an all zeros output from the printDetails() function you can bet you are having a communication issue between the Arduino and the nRF24 module.
Start by checking your connections.
Check your connections again, using a multimeter to ensure continuity.
Check your connections again (no, I'm not joking).
Finally add a capacitor (anything between 1uF and 100uF will do) between the VCC and GND pins of your nRF24 module: those modules are pretty sensitive to voltage fluctuations and they are subject to current consumption spikes at startup. 
Pair that with a possibly not state of the art voltage regulator (especially on cheap Arduino clones) and you end up with a non responding nRF24 module: the capacitor will provide the extra juice whenever it's required by the radio module.
This is such a common problem that I started soldering the capacitors directly onto the modules to save breadboard space!
