I have just purchased VWD 2 and loaded it into Poser 13 without problems or error mesages. I need to get the hang of the interface, of course, and get it to do something useful, but so far, so good. I had LaFemme 2 and a prop dress imported into the workspace, but trouble to find that 'simulate' button. 

Only trouble i have had is that apparently the Poser library does not work (stays blank) if VWD is running.

I also checked the scripts. They all come as .py, so readable code and not in a binary encoded form. I found in the code no things that would not run within Poser, except one function call I did not recognize.

More to come. I will keep you all posted.
