Help for building a server Garry's mod (murder)

Hello,

I reinstalled my gmod server, I copied all my custom files into directories, i’m actually trying to set playermodels :\ without success !
I fixed spawns/loot problems on md_clue.
I actually have problems with implemantation of FastDL, playermodels, PS, etc.
I’m using a dedicated server on Debian Wheezy.

Thanks for any reply.
