Arduino Mega and Rainbowuino v2.0

Hi,

I am attempting to program a Rainbowuino v2.0 with an Arduino Mega.

I have connected up the tx-tx and rx-rx and other wires as specified, but I am having no luck getting it to work.

The error I get from the Arduino IDE is as follows;

avrdude: Expected signature for ATMEGA328P is 1E 95 0F
Double check chip, or use -F to override this check.

Any ideas? This is driving me insane.

Thanks,
Daniel.
