Need help with rendering cloth in metal ray

[ryannichols]

I'm new to 3Ds Max and using the message board so I apologise in advance. I am working on a scene for a demo real and I can't get the curtains to render. I baked them after simulating them. I took out the motion blur associated with them. I have checked the render options and still can not get them to render.I used the tutorial at http://marlev.deviantart.com/art/Making-of-curtains-in-3ds-Max-117249472 to create the curtains, the render setting for the scene is Metal.Ray.no.gi preset with force 2 sided option enabled. I have uploaded part of my scene to my DropBox public folder that I am having trouble on if anyone wants to take a look at it. it is the zipped file that is titled post. I am using 3Ds Max 2012. Any help would be great, Thanks
