I had to do a full install, not as bad as it sounds!

Assuming you have all your Vue files inside MyDocs then it is painless!

1 Place your e-on folder in a new folder called Temp or whatever, inside MyDocs.
2 Uninstall Vue from your pc.
3 Re-install Vue using it's normal parameters, i.e. MyDocs for files, Programs for system.
4 Delete the new install folder from MyDocs and replace it with the one you saved earlier in the Temp folder.
5 Job done!

this does work, I had to do it earlier when my Poser imports stopped, the pz3's would come in but weren't using any Poser shaders or textures even though I'd ticked the box!
I didn't lose anything with this method!

Injustice will be avenged.
