Faceposer is missing

I really need some help with this, I’m not sure what to do. In my Gmod when I open the Q menu and go through all my tools, my face poser is missing, its just gone. I’m upset because for awhile now I’ve been practicing machinima and thinking of ideas and was about to start working on something. All of a sudden my face poser is just gone and that REALLY messes with my machinima plans. I really need help with this, and I know I might have to uninstall then reinstall gmod but if theres a way around that I’d highly prefer it. I have about 10 GB of stuff for gmod and I don’t want to have to reinstall all of it. Please help me, Thanks for reading.

P.S. I don’t know if this messes with anything but my computer is a Vista 64-bit if that changes anything.
Please help.

I would reinstall it.

I agree with mescool. Any addons you want to keep, copy and paste them into a seperate folder and completely reinstall GMod.

Or you could try deleting local content.
