Xerxes will do, thank you!

Mondor04 also have this problem but the contract still costed me cod points but I counted that I completed more than double the amount of Kills the contract wanted me to do

I consider this a definitive solution so you can try it.

First of all you need these configuration files

Once you have downloaded the text files you have to place them in the following location: %localappdata%\Plutonium\storage\t5\players

If the “players” folder does not exist, simply create it

copy and paste, very practical, right? -

SHLOWW5.0 You're welcome

Now I want to pick up some Dual Wield CZ-75:s... for science

Hadi77KSA Well I had the same error as this user, using the files you sent in that post I managed to solve the error, although I guess you are right because the numbers and letters are different in the exception code, although the user can try, in case it does not work I would apologize for not being helpful enough.

Got up to level 31 offline now I lost everything

So, mine fixed itself doing this: Unlock custom classes, quit the match and go back in. it will kick you, and for me also put me back to the rank before the unlock. Fully quit BlOps1 and plutonium. Load it up again and re-earn thew rank. Choose a custom class in the same match you unlocked it, from then on it was fine. IDK what step fixed the issue, but it did

Anyone have a solution for this?

Buy the game on steam to get clean files.

Resxt Yeah, saying "It works for me" isnt helpful either lol, thats great you can play it but adds literally nothing to the conversation, people respond the way OP did bc people like to give time wasting answers

Just click on the game folder if thats the problem, dont go into it. If that isnt the problem then i dont know what to do.

Its a common well known issue. Just don't pick it up.
