no gun sounds?

hey, i'm setting up a hlds server for me and my freinds.

i have everything installed, amx, metamod, and csdm 2.1.2

but when i enter my server it says error: bad file server needs file sprties/scope_arc.mdl

so i put it in my sprites folder and it worked, but when i enter the server there are no guns sounds. i can hear knife sabs, walking. but no gun sounds. it only happens in my server.

(if i go to diff server, i have my gun sounds)

help would be nice...
