yes, i am using 1.49.01, see my signature

i asked for your configuration because i thought that the memory insufficiency could cause the problem, but i guess 4GB is just enough. sidenote: while rendering, my task manager shows that sketchup grows to ~1240MB of RAM allocated. i also can understand that saving and reopening the file is even more upsetting in your case, since the 120MB scene takes ages to open...

the second issue i thought of was that maybe just the scene parsing and light cache warming up is taking place (which could be checked by looking at task manager and watching the cpu usage).

but now since there are already two people with the same issue, it's really becoming strange

missing sofa - i honestly didn't notice, i touched no layer settings, i just moved the camera around and copied the spotlight objects (which are shown in Outliner as Vray IES Light).
EDIT: seems that although the sofas showed in SU's viewport, the Layer0 was turned off, and i had to turn it back on so that they are rendered in vray too.

editing the chandelier rectangular lights - no crash, edited its color, ran the render... no problems. although i don't think this is how it should look like.

Thanks guys for the help. have not yet solved the problem, but if i do i promise i will put it up on the forum so someone else will not face the same misery

i opened your scene, and so far i've been copying lights around and vray always rendered for me o.O

if after closing and opening sketchup it works, do you think this could be a lack of memory issue? what is your pc's configuration?

EDIT: also, are you sure nothing happens after the flicker? maybe the scene is just being parsed; the task manager doesn't show any cpu usage?

Hello! I have a similar problem. you click on the render button and it remains depressed for a little while and just comes back. The render window does not open at all. I have rendered much more complicated scenes on this pc, so the configuration, i guess should not be a issue. but i am not sure. this came to my mind too. someone please help. i am stranded with a very elaborately modeled scene and i cant render it.
