Well, I have worked out that it is only scene's with imported objects ( including VOB's) that are causing the problem for me.  The last two pics in my gallery were done in  Vue 6infinite, the second after I patched  it, and I can still reload, change and save them, no problem.   With any scene with an object in it I can keep on saving it but when I close Vue and open up the saved file later, it will load fine and render but will crash on trying to save it again.
BTW I was only able to do the mountain one because of the patch, it solved the problem of Vue crashing when displacement mapping was used!   Swings and roundabouts:)
