Models on players not working!

Okay so I have DarkRP setup on my server, and I added custom classes. I am having trouble with these three models not working on players:
models/player/Eli.mdl
models/player/ct_sas.mdl
models/player/ct_gign.mdl

The other models I use are fine. Eli is from HL2 and the other models, are from CSS.
It is very annoying as the player looks like the ragdoll but as a pinup where the arms are extended at shoulder height, and the player will just float across the ground, not actually walk. Is there anyway to fix this? I need an answer a.s.a.p :confused:

They’re:

models/characters/Eli.mdl
models/player/sas.mdl
models/player/riot.mdl

I’m not sure if the Eli one is right though.

oh sweet. Thanks. I’ll check it out right now.
