hi and help with hdri

[biancaneagu]

Hi, guys. It's my first post ever, so a big hello. Often found here solutions for my beginner troubles. Now I am sure my question has an answer somewhere here but I am under a lot of time pressure and I found too many posts with "HDRI PROBLEM" tag.

 

So here is the trouble.

using: 3d max 2012, vray 2.0 and a bloody night scene HDRI for my night scene.

 

For some strange reason, I cannot see my HDRI in the viewport and therefor, cannot control my scene. I tried all the possible things, now what I did, I exited my scene, and opened a new one, put some balls with some stuff, a vray plane, another HDRI, a vray dome light. Of course, same result. But now, when i try to check the "use Environment Background", it would not let me select it. Vray renders my HDRI and all things are in their place, I just need to move it a little bit, which now is impossible.
