dspic basic program doesn't work

hi,
I've recently purchased a dspic33FJ06GS202.

I've written the following code just as sanity check, but for some reason it just doesn't work.
Pickit2 programs and reads the program well and the voltages also seem to be fine. I thought maybe the clock doesn't work because I don't put any fuses, but I doubt that this is the reason.

You have the answer already:

"I thought maybe the clock doesn't work because I don't put any fuses".

thanks for the answer Ttelmah,

I've tried the following and still no luck.
Am I configuring the device wrong?

The problem is that quite a few of the fuses default to values that can/will cause problems on these later PIC's. Copy a basic setup from an example, and see if it starts.
