Parallel LCD - broken module, or broken software

It's been quite a few years since I've gotten down and dirty with SX programming.
I've recently gotten a parallel LCD off Ebay. I've tried the example code in the downloads section, changing the data port to RC, and the control port to RB. The LCD doesn't work. Before I email the seller requesting a replacement, I'd like to make sure it is in fact the hardware malfunctioning.
Does anyone have a parallel LCD that they can test? I am attaching the modified code.
RB0 -> RS
RB1 -> RW
RB2 -> E
RC0-7 -> DB0-7
Thanks in advance,
Alex G.

ps: don't forget the pull-down resistor for the e pin.
That pull-down was giving me the headaches. It all works now.
