Plutonium

Your path has invalid/special/non english characters

Probably a network issue
Check your firewall/antivirus/DNS or use a VPN

Cloudflare WARP or a regular VPN will do for example

Piracy is not allowed, you won't get help for it

I guess you mean T4: World at War. IW4 is MW2

You might be kicked for being votekicked, banned, playing a disallowed weapon, camping, insults, ping too high and a bunch of other reasons
Better ask the server owners directly

There is no such thing as "the mod menu"
If you downloaded one yourself just read the instructions

There are .emblem files in %localappdata%\Plutonium\storage\t6\players
Might be worth a look

To host a dedicated server you need to own the game on Steam
Owning it on another platform doesn't work

cardtitle "Hi" and icon is custom avatar from the forum that you then use in the callsign section thingy in-game

Piracy is not allowed

Play solo/custom games or the few servers that allow VPNs

Follow each other on the forum

Try CTRL + F5 or clearing browser cache

unclepushy send the full path before the players folder to make sure you are at the right place

Try this in the console (wait a bit for it to take effect)
r_fullscreen "0"; r_noborder "1"; vid_restart

"I committed a crime and went to jail for it but now that I am in jail I understand the lesson and want to get out early, pretty please?"

Not how this works

Make sure your game is closed before doing that.
Go to %localappdata%\Plutonium\storage\t4\players
Open the config file with the notepad to edit it.
plutonium.cfg is for singleplayer/zombies and plutonium_mp.cfg is for multiplayer
Change these 4 dvars to be like below (you can use ctrl+f to search for them)

seta r_fullscreen "0"
seta r_noborder "1"
seta vid_xpos "0"
seta vid_ypos "0"

You should always play WAW in windowed borderless to avoid alt tab crashes and vid_restart crashes

To play DLCs install them. No game files are provided and no "DLC unlock" is provided either

I assume you mean dvar values

You can have a GSC script that sets the dvar

Init()
{
SetDvar("g_speed", 500);
}
