How to use the microchip dsPIC blockset in MATLAB??

The microchip block sets for the dsPIC controllers are available on the webpage www.microchip.com. These block sets can be configured and the model file thus created can then be compiled in MPLAB ,thereby generating a C code. I am making a dc-dc converter using dsPIC30f4011 controller. When i tried to use these block sets in a model file in MATLAB i got the error as written below.

Error due to multiple causes: block_diagram does not hava a parameter named 'MCPATH'.

I am using MATLAB 2009ra. kindly let me know the reason for it.

Jil: It might be best if you contact the vendor of the blockset for support.
