3d mouse 3dconnexion all of a sudden not working in keyshot?

[dkittl20]

Help!
My 3d mouse no longer works in keyshot.  It works in all other programs!
I go to preferences and the interface for 3d mouse is grayed out.
Ive updated keyshot,  messed with everything in the 3dconnexion control panel. still cant figure it out.
any ideas?
