Trouble with EA DOGS104-A LCD Display Module

I am attempting to integrate an EA-DOGS104-A LCD character display, so far I have had no success.
Does anyone have experience with this part?

I am using a PIC18F24k22 MCU, programming in C.
Using SPI to communicate.
The MCU runs from +5, the display has it's own 3.3V regulator.
I am using a resistor divider to do the voltage level translation.

I have been checking every detail I can think of, but the display does nothing.
I would have better luck connecting my MCU to a block of wood.

Thanks!
