Gmod missing TF2 props

Hello, i have tf2 installed along with css, DoD and my gmod works perfectly fine apart from the fact that i downloaded a tf2 addon thing from garrysmod.org and after i added that NONE of my TF2 props work on gmod. i reinstalled gmod and i removed the addon and still nothing

what can i do?

Play TF2, go back on GMOD.

You’re sure it’s mounted?
