MSP430 and Sparkfun Serial Enabled LCD

Hi,
I'm using a msp430f169 and the 3.3v Serial Enabled LCD from sparkfun. So i should be able to just send a ASCII to the LCD and it should be displayed. Nothings happening on the LCD though. I checked that I am sending at 9600 baud so I don't know what's wrong. Any ideas?

Do you get the splash screen when the LCD is first powered up? Have you tried changing the contrast?

I figured something out.
The LCD I bought was a 3.3v one but I get the splash screen when I power it with 5V. 3.3v logic is still not working on it so did i just get the wrong lcd or does the 3.3v lcd still only work with 5v?

Ok
I adjusted the contrast to pretty much maximum and can barely make out the splash screen at 3.3V. Backlight control commands that worked before are no longer working now.
