I cant get any lighting to work!

I am following the Vray for Rhino manual and have followed all of the steps but when i render, the rectangular light i create has no effect. I have tried multipying it and messing around with the GI but cant figure it out! Can annyone help??

Thanks

Chances are you have an older version of V-Ray which has the physical camera enabled by default. Please download the newest version of VfR and give it another shot.
