Total newbie...dumb question...patience please!

[xxxMikexxx]

Alright. I feel pretty intimidated by this site because I know very little about computers. I'll probably get booted off this thing for my ignorance, but I will post my question anyway...
I downloaded the blood ?patch? for my MOHAA and am trying to make it work. I need someone to play dumb and spell out these instructions to me in terms I can understand.....Install:
****YOU MUST OPEN PAK2.PK3 WITH ANY ZIP VIEWER IT IS IN ZIP FORMAT
BY DEFAULT IT IS LOCATED C:\Program Files\EA GAMES\MOHAA\main
THEN ADD THE FOLDERS INCLUDED IN THIS PATCH TO IT (MODELS, SCRIPTS, TEXTURES)

I kno I have these files, but I don't have the knowledge enough to gorify my game. Can anyone help? Thanks.
