I thought that was what you meant, so I re-exported the deckchair into the Multiverse folders within the Documents subfolder, with all the other assets, with the same results.
What I will try tomorrow, is to reinstall Multiverse, and allow it to reside within the OS directory system, to see if this is the fundemental issue, or at least eliminate that, and report back. At least that way, I am working from the same baseline as everyone else.
