Go to PMD Editor's folder, plugins and put these two files in User
I... I already did that, like it is said in the tutorial 
If I´m still asking such question after reading it, it´s obvious because didnt work. After "User", the only thing is "mQO" or alike.
Sorry if I bother you too much 
Then try copying them to the "System" folder too.
Still nothing... I wonder what I'm doing wrong.
