Vray won't render

[itasurfer]

Hello everybody, I'm a student coming from Italy, a beginner with Vray for SU and I was surprised by its potential!
By the way, after some nice renders, I had a situation similar to this, with the vray button pressed that won't render!

I'm having issues with the new V-Ray fSU (v1.48.66).
But the biggest one is when the VFB doesn't show up, i.e the rendering process doesn't start (as discribed here: Link)

I'm trying to find the cause for this in the "Error Log", but I don't know how to find the error indicator among all the text in the log.
My question is what should I look for in the error log in order to understand the cause of not being able to render?

I've uploaded the Error Log of the problematic scene: http://www.mediafire.com/?ojdyixwabkk

My log is short though, hope you can help me!
Thanks!

Plus, I would appreciate to know how to render to file, that could be very appreciable!
just like thomthom said:

You have the option of rendering to file, that preserves memory better and allows you to render larger models in higher resolutions.

Many thanks

Re: Vray won't render

All right, I got over the problem by using a backup file I made before some changing.
I stiil wonder about how to render directly to file though!
thanks again
