need Dayz Installation help! Please, anyone?

i used to play dayz all the time, and then eventually i got really tired of the hackers, i decided that i would try and hack myself, and get revenge on those little cheaters. but of course, im not really a computer expert, and i got myself banned....thing is, now i just can't stand not being able to play anymore. So, i made a whole new steam account, repurchased arma 2 and operation arrowhead, and i got really confused from a couple of tutorials on you tube about the installation, so i looked up how to download via DayzCommander. i downloaded dayz commander, and installed it, and ran it. but it said i was still banned? all i did was install dayzcommander and not the game itself, but the tutorial didnt have that in it so i figured it came with it or something. I'm willing to do anything to play, and any help that will get me into the game will help. thanks!
