I do install DSON importer.
My poser Pro 2014 could open .duf files,
but it can not open any .duf file anymore now.

There is no error message but just load in figure Andy2.

PS:

I have tried to re-install DSON importer and Poser Pro 2014. 

PS:
DSON's log file is shown as follow

PS:
When I could open the .duf files,
the log file is shown as following
