Thanks!!!

It finnaly worked.

I did overwrite the files...and it worked.

I don't know how much I can thank you!

Please, I heard there is like 1/10 people with this problem.

I hope they see this post.

I am pretty sure that I am the problem. I am just asking for help to resolve it.

First, when I join a server, I don't see the image of the main title, I see black and purple squares.

Second, I don't see the icons ( I don't see the items in the detective/traitor shop and on the dead bodies ). Still black and purple squares.

Help menu is black and purple.

At last, when I try to aim with a scout/AUG/Sniper, my screen becomes black and purple.

Before, I could play the game without any problem.

I have Counter-strike source , Team-Fortress 2 , Portal 1 and Yeah You guessed it, Garry's mod.

I reinstalled all of my games, I restarted my computer multiple times, Tried to put back a working back-up,Verifying the game cache files for every single games, I tried multiple servers,etc...

Without success.

I require your help to be able to play this awesome gamemode correctly.
