Arduino Pro Micro NRF24L01

Hello, I am using the RadioHead library with an Arduino Pro Micro to make two nrf24l01 transceivers talk to one another. The problem is that when I startup my sketch, it says Init Failed.

Does anyone have experience working with the RadioHead library on the Pro Micro?

I have attached a picture of my schematic. The SDA and SCL will go to a Gyro module not currently attached.

The Pro Micro uses the same chip as the Uno, it won't be Pro-Micro specific unless its inadequate
3.3V power causing the problem.

My Pro Micro uses the 32U4 MCU.

I have not tried to get my nRF24s working with the Pro Micro but I had no trouble with my Leonardo which also uses the 32U4.

I have only used TMRh20's RF24 library as in this Simple nRF24L01+ Tutorial
