Hi all
I had a copy of Vue 7 PLE on my computer.  I uninstalled it and put Vue 8 Pioneer on my machine (its a free educational version) to try it out. Played around with it for a while and everything looked good.
Then I forked out cash Vue 8 Frontier (the base pack) with a view to expanding over time, and I started by redoing what I'd done in the first version. However every time I try to load an ecosystem material (create procedural terrain > click load material > Material Layers > Ecosystem Layers )(which worked fine in Pioneer) I get the message

This version of Vue can only read content that is locked to your license. Non-locked content will be replaced with dummy objects.
If you wish to import non-locked content, please consider getting the 3dImport module.

Note: I'm not trying to import anything, I'm using the stuff that was loaded by default with Vue.
I searched for the 3Dimport module they mentioned but to no avail.
A bit pissed off by this I went back to Pioneer (which, remember, had performed the operation perfectly before (and for free)) only to find that that too was now giving me the same message.
So I uninstalled everything and started again with the previously happy Pioneer only to get the same results.
Right now I feel like I've been the victim of a bait and switch scam and I'm out $100.
I'm hoping I'm wrong though and  that it is just my stupid noobness that has made this happen.
Can anyone help me?
Thanks
