Hi,

Well problem is solved and the answer couldn't have been more simpler, I can render spectral atmospheres on all render cows with no problems.

And the answer from tech support was :

Right click on Vue 6 and run as administrator!

I am using Vista, wish they could have told me that sooner :)

But anyway working now.
