Can't Export 3D DWF in 9.1

[rolandwebb.com115367]

Has anyone else encountered a problem in Revit 9.1 when exporting to 3D DWF. My project file contains various linked Revit models, but refuses to export to 3D DWF. When I unload the linked Revit files it works. Exporting to 2D DWF works fine. This problem was not an issue in release 9 or 8.1. Any ideas how to solve this, or is it a bug in 9.1?

I could be mistaken, but I think Autodesk fixed this in a later build of 9.1. Which build are you using?

I can do it just fine:
