Vray Rendering Problem

Hey im using vray 2.00.01 and 3ds 2011 sp1 and im having this issue where i need to have both a blurry reflection and caustics in a scene. I have GI on with refractive caustics and also Direct light caustics enabled. The scene is lit with a vray plane light. The issue is that for some reason if both GI and direct caustics are on the nice blurry reflections on my materials disappear . I have no idea why this is there are two quick example renders i did attached.

Any help or suggestions will be much appreciated, thanks!
