moh blood patch

[mal]

i know this is probably old hat,but i downloaded the update patch 1.11,and the extra blood patch.i now can play moh without the cd,but the blood patch doesnt work.
i unzipped it with winace,extracted it to the folder MAIN in mohaa,which i was told to do,but i dont see any blood at all in the game,perhaps i havent done it right?do you put the folder in main,or just the files which are in the folder?
could someone help me out here please?
