Large Resolution Rendering

Im using VRay Edu with Rhino 4 Edu. Im trying to render something in the 5000x6000 pixel range but regardless of what I enter in the output options fields, it never renders above around 1400x1600 or so. Is this a limitation of the Edu license? My friend downloaded the demo versions and was able to render at full size by just entering the dimensions. My computer is newer and more powerful than his so its not a hardware issue. Thoughts?

Re: Large Resolution Rendering

Yes the EDU licenses are currently capped off at 1600x1200 or 1200x1600
