Quote - None of those apply - I just followed the Daz instructions.

This morning I deleted all the files relating to this figure (Bot Genesis), went back to Daz and downloaded them again using the installers as instructed.

But the error message is still there.

So ... is it worth deleting ALL the Daz stuff from the drive and starting again?

The DSON importer generates a whole bunch of temporary files. These are odd for temporary files because they seem to keep hanging arround.

On my system they are in my Poser content folder. For me this is Poser Pro 2014 ContentRuntimeDSONauto_adapted. Much of the temporary stuff has unique keys associated with them which are of the form '7cd4c5f0-213d-a94d-4692-89b851efa914'

Rather than delete the folder with the Bot Genesis installed I would suggest looking at the auto_adapted folder. In the data folder under auto_adapted you should find the temporary .obj and .pmd files. On my system they are grouped into folders which take the name of the author of the model. As an experiment I would first delete the temporary files. This would give the importer a chance to re-create them.
