I have the same problem with going back to older designs often. The script does what it should in a fast and simple way. It helped me a lot! Thanks!

Yes, I have noticed that as well, although an error window showed up when two or more sketchup files were opened.
In this case however there is only one file opened and the render doesn't start.
The V-ray is 1.49.01. I tried reinstalling it once, but I guess I'll have to do that again and maybe this time it helps.
One more weird thing i noticed was that the v-ray options window showed up blank without the system, camera, and all the other bars.
Only after clicking on load defaults did the bars show up.

Hi to everyone!
I have a similar problem - that is "v-ray is currently processing your scene..." shows up, bu then disappears and no frame buffer shows up.
I have had that problem with very heavy scenes before on a different computer, but this time it happens in a raw scene with just the standard 2d person in it.
The problem occurs on a laptop with the following hardware: processor T5500 1.66Ghz, 667 Mhz FSB, 2Mb L2 cache; 2.49 Gb RAM; graphic card: mobile intel 945 GM. free space on disk C is 9.03Gb.
Do you think it might be a problem with the computers parameters?
However sketchup itself is working without problems on this laptop.

I hope someone can help me with this problem. Thanx in advance!
