I have a thread in the Discord as well but I wanted to make sure I could get as much help as possible.

When I (or any of my friends) attempt to join a modded (promod) server that I’m self hosting, we all get the “Impure client detected” error.

When I host a normal server with no mod, server runs great, everyone can join and play.

When I added the Promod mod (promodlive220\_eu), we all now get this impure client error. None of us have modded .iwd files in main, I’ve fresh installed on Steam several times, I even went as far as installing the .iso and manually patching + manually updating to Cod4x - all without any change.

My shortcut properties for the server.exe is as follow:

```auto
"C:\Users\74u\Desktop\Cod4X Server\cod4x18_dedrun.exe" +set dedicated 2 +set sv_punkbuster 0 +set rcon_password "$password" +set net_ip $localip +set net_port $port +set sv_maxclients 16 +set fs_game Mods/fullmod +exec server.cfg +map_rotate

```

Below is my server.cfg file, which is placed inside server/Mods/promod directory.

```auto
/ promod live v2 - sample server config v1.4
// for public ruleset customizations, see z_c_r.iwd

// info strings
sets _Admin "fully"
sets _Email "discord @74u"
sets _Website ""
sets _Location ""
sets _Irc ""
sv_hostname "^1Fully's ^7ProMod"

// server settings
sv_authorizemode "-1"
sv_floodProtect "1"
sv_reconnectLimit "5"
sv_pure "0"

// welcome message, message of the day (motd)
scr_motd "Join us on Discord!"

// player slots, maxclients - privateclients = public slots
sv_maxclients "12" // maximum number of clients
sv_privateclients "" // number of private slots

// client download settings
seta sv_wwwDownload "0" // enable download redirection
seta sv_wwwBaseURL "" // defines url to download from
seta sv_wwwDlDisconnected "0" // disconnect clients while downloading

// map rotation
sv_maprotationcurrent "" // leave empty
sv_mapRotation "gametype sd map mp_strike map mp_crash map mp_backlot map mp_vacant map mp_district map mp_broadcast map mp_crossfire"
sv_randomMapRotation "1"

// promod settings
promod_mode "custom_public" // promod mode, for a list of promod modes see attached readme
promod_enable_scorebot "0" // match-modes only

```

Any suggestions or insight would be greatly appreciated.

This is set to 1 somewhere in the mod files, promod does not allow skins etc by default.

I actually found out that I had the wrong server files.

Once I grabbed the right server files from [the releases](https://cod4x.ovh/t/cod4x-releases/24) and took the zip, put them in a new directory, and moved over all my files from the Steam installation of main and zone, everything worked exactly as expected.

I guess the files I originally grabbed from Github were not what I needed.

Or I deleted something on accident.
