I installed the plutonium launcher and when it said setup i had to put an file into an folder but i didnt know in what folder so i created a new one and put it in there. After that it said i can start mw3 but now there is coming an error every time i try to started it. I didnt know what to do so i deleted the folder where i tried to drag the files in because it was empty what do i have to do know?
