Face poser doesn't work!

[Wolfy Snackrib]

When I try to open face poser it just says "the configuration information for the game youre trying to edit is invalid or missing"
and the options of the box is Run away, cancel or more information. How do I solve this problem?

Create a mod from the steam main menu.
Once done, make sure it is selected in the drop down and run faceposer again.

voila!
