i think aim is leading u wrong... all i had to rly do was download BitTorrent for the ready-to-play client from alteriwnet. i download the 1.3.37a patch and extracted to my mw2 directory. (u need to put in steam directory even tho u dont have real game) When u run iw4mp.exe an updater will show. there was a bug when alteriwnet forums uploaded it, so i had to download a file called iw4mp.cfg to fix it. I know this cuz i also have cracked mw2. TIP: if u fuk up yer mw2 files, always ALWAYS make backups
