AndreTOQU3 i am just a regular user like you but i've been here for a few years now and i don't think i've ever seen them unban anyone. It would just be too hard to know for sure if someone was telling the truth so it's better to just have a universal policy. It's not like there is a team of 30 people working for plutonium who have time to review ban footage and call a tribunal to deliberate and make a vote on unbanning.
But that's just my guess, i dunno...
you triggered the anti cheat twice... the first time is 7 days, the 2nd is permanent.
you want BOTH the above to be public but...
family share copies work fine, and it looks like the game is listed in that picture you posted... what is it that is not working that is making you think something is wrong?
Lyn_ if you disagree with the post above you then you should re read what i said.
It is a FACT that plutonium was designed to run on windows. The fact that it works on some linux setups is GREAT! but not the point of the project.
If plutonium running on linux was the point of the project, then it would be designed so that the anti cheat didn't conflict with the way HWID works on the older steam decks.
This is a compatibility issue... that's the point! It was never created to run on linux/steam decks. Just because it CAN be made to work on some setups does not mean that the dev team needs to put in extra work to make it work on all of them.
I got nothing against the steam deck... i hate too that it doesn't work on it, i'm just saying there are TONS of popular platforms / gaming machines that plutonium will not work on either because it is not what the project is intended for.
Jxrdanb you'll need to log into the account that it is linked to and unlink it. then you'll be able to link it to another account.
If you can't remember the credentials to log into that other account, you'll need a mod / staff to help, but you'll need to have proof that it is your account of course (plutonium and steam) but even then i don't know if they'll be able to help.
drpissman434303 discussing politics here is specifically listed in the rules of things not to do... so we should try to keep the conversation to the textures and not anything else 
Reign47 this looks like an antivirus blocking issue
Strage no one from plutonium is blocking Russia. If your government is blocking certain websites or connections then you can use a VPN.
Plutonium does not block VPNs. if you are unable to connect with a VPN that means that that particular server owner does not allow VPNs.
It is not plutonium blocking you.
gamer_live can't help you with those files anymore... things changed 3 years ago when activision started shutting people down... now plutonium only provides support for steam files.
If you get the game from Steam and use the "game settings" button to point plutonium to your steam game directory, you'll be all set!
anflous46 sounds like you have a russian copy of the game... changing a language specific copy of the game is a little harder than normal language changes.
For the missing maps... it seems you don't own the DLC maps. Those maps are all extra content that you need to purchase as addons to the base game.
that's usually because of one of three things:
you have it hidden:
you have a filter set:
or you got it from steam rip and not the actual game.
anflous46 language changes are done in steam... right click on the game and click Properties, then General, then change the Language:
Edit: TIL more about the Russian version (see Hadi's post below)
Atxmicsz you likely need to install multiplayer. this error is usually because you only have the base game installed.
get the games you want to play on steam and then point plutonium to their folder and you'll be all set! Plutonium doesn't make the games appear in steam, you have to have them.
Gxnfeed plutonium doesn't control what happens on servers... the server owners control their servers and can ban for whatever reason they want. If they are banning you for stupid reasons, then it is a stupid server... just go find a better one.
Or find that server owner and tell them you think they are a poo poo head... maybe they'll change their ways 
Vzz.X you know the forum has a search feature right?
unknowghost really
gamer301 you have pirated files, those are no longer allowed (changed 3 years ago).
get your game from steam, use the game settings button to point the launcher to your steam game folder, and then click play and you'll be all set!
assuming your ban is on steam and not plutonium, then yes. but you might want to read up on plutonium's anticheat policies: https://plutonium.pw/docs/anticheat/ and don't get yourself banned from here too.
it should tell you how much longer when you try to login. The length for the first ban is 7 days. if you create more accounts to try to get around that, it will add time each time you do that. If you get banned a second time the ban is for life... but when you try to login, it will tell you how much longer you have.
