ABetterMyk

First of all i have no idea what i am getting myself into, i have little knowledge of downloading this game. i just followed instructions on this youtube clip:http://www.youtube.com/watch?v=ljyzbL_jt5k I downloaded Arma2 using torrent, installed it and everything, patching it to the latest then i clicked on dayz_game and then i got in, joined a server but when the loading screen is running i get this weird message saying a list of files; dayz_anim.pbo dayz_code.pbo dayz_equip.pbo dayz_sfx.pbo dayz_vehicles.pbo and that i needed to delete it or somethig so i quit the game and deleted those files. but when i clicked on the game it says: 'Data file is too short 'C:\Program Files (x86)ArmA2/Expansion/addons/characters_e.pbo'. expected 673569908 B, got 24381440 B and thats what i am currently stuck right now. I would suggest those people who knows how to download this game using torrent to watch the youtube clip i linked above so you can tell what went wrong and all. please i really need your help, i wanna play this game badly!! EDIT: wait now i deleted the characters_e.pbo (i saved it in another folder just in case i need it) and i opened up the game and well it loads but when i join a game it says i have bad or invalid CD keys
