VRAY rendering all black

Hi guys!
New here and already having problems haha! Hopefully you can help me out. I have to render this building, the courtyard in particular (as shown in the camera view). I’d like to have it as though sunlight went through the holes present in the façade, producing clear, strong shadows… however, whenever I render the scene in Vray, I get a black render window I’ve tried the default scanline renderer and mentalray, and both show some results (although not what I’m looking for, at least it’s not black!) I’ve also tried making the lights cast vray shadows, used vray materials… nothing.

BTW I’m using vray 1,50 sp4 and 3dsmax 2010. Any help is more than welcome!
Here’s the link to my .max file:

Cheers, I’m really desperate!

if your using the full version you can send an email to chaos for full forum access and you really should go to your download area of the chaos site and upgrade to sp5. im assuming your using vray camera? (i dont have 2010 so cant check the file)
