Plutonium

It is obviously your Plutonium password, as you are on the Plutonium forum. You didn't enter the correct password if you're getting a "wrong password" error.

To verify your email, first, you need to set your email on your Plutonium account.

To do this, click your profile in the top right corner on the forum, then click "Edit Profile". Here, on the right side, click "Change Email" and enter the email you want to use and your current password, then click "Submit".

Shortly after, you will receive an email from Plutonium with a link that you must click to verify your email. Click it and you're good to go!

Check your account info, you should see an email history with your email in it, if you do have an email address assigned.

Your friend never actually confirmed his email address and therefore his account does not have an email address assigned to it. He cannot reset the password. Unless he remembers it, the only option is to create a new account.

I suggest using a password manager in the future.

dante9 That is the problem, guaranteed. Find a way to do it.

Make sure your windows default audio output is the one you want to use for the game.

What happens when you start the regular game on Steam?

You did not get banned for entering your password wrong too often. You got banned because you cheated.

What kind of ban? Anticheat, server or Discord?

Us and the free version of the MW3 dedicated server tool on Steam only supports Multiplayer. If you want to play Singleplayer, buy the game.

Fix your network setup.

This usually indicates a connection issue. Check that nothing is blocking the updater's connection, like your Antivirus or your ISP, try a VPN and see if that works.

Plutonium doesn't provide game files.

If this happens, this usually means you've been banned before and are trying to join on an alternate account.

Not American, but thank you for your future service, and safe flying!

No. We don't take client contributions. All clients, save for GH3, use our bootstrapper.

We do not support Steam Deck. Since every Steam Deck is identical in hardware it's effectively incompatible with our anticheat. Recommend you don't attempt to play on it.
