Problem with Deep Exploration Renders.

I tried importing my sketchup model into Deep Exploration again to see if the HDR renders would work. Also tried researching on the net to see if other people were having the same problems but couldn't find a resolution. So I tried rednering them again and unfortunately it was still stuck on 0% for ages and didn't seem to be going anywhere after 20 mins. This is really really frustrating! I will just have to use the initial raytracer renders that I posted earlier for my hand in. Grr.

Note: I've relabelled my earlier renders as "Final Renders-Problem."
