Cross Studio and Jtag

I’m using Cross Studio and the Jtag from Sparkfun.

I am trying to connect to the LPC2138 board through the Jtag for debugging.

But there is an error when i select the “Target-Macragor Wiggler 20 pin”

The error is: Cannot open ARMD device Driver.

Why is this? and if i need this drivers where do i get them?

why not ask Rowley first?
