I ran the demo .veg from the Chienworks website, and it looks like VV crashes even before invoking 3D LE for anything. What i mean is that the problem is not in 3D LE. Probably someone from SoFo can try it out and see what's going wrong.
About the RAM set to zero, it is necessary ONLY for refreshing the preview window instantly when you enable/disable the pivot control (in the 3D LE dialog). When rendering the RAM option do not affect anything. So if you get a crash when using 3D LE it is not related to the RAM setting. Please try out a few times and see if the crash can be reproduced. If someone can give me a sequence to reproduce a crash then i can fix it.
