Refl

Hi, I'm new here so I'm not sure if I've made this thread in the right place (also my English may be a bit bad) so I apologise.The reason I've started this topic is for help on my situation. So, yesterday , just like any other day, I've finished playing DayZ and after browsing websites etc, etc.. went to sleep. In the morning I've tried to log on to a server I'm playing in and I've got a message that I have been global banned. Same went to all servers I've tried connecting too.. At first I was "what? for what? I haven't done anything!" but as we all know there's always a back and more dark story to all this. As I'm new to this game (got this game 2 weeks ago) I was bound to learn all things the hard way about this game. So what happened? As many mistakes I've made in this game resulting in my (ingame) death. I've allowed something NO ONE should allow to happen.. Bandits took better of me. I never waned to be a bandit nor do I still want. If someone needed help and I could - I would, but that's different story. After I was lied into helping someone(bandits) and after that get killed for it, I woun't lie, I was pissed. And then It happened.. As there are lots of hackers in this game as well as the mod itself is still in development, I thought the downloading a hack that would help me teach a lesson to the bandits wount hurt, but it did! Not only the hack didn't work, after 2 days I got global banned. Guess bandits win and I lose. Not much can be said about this, as my own action lead me to this and as much as hate to say it, it's all my fault. Long story short - I hacked , I got banned. All I'm asking is this: Do I need to buy ARMA 2 Complete Collection or just ARMA 2 Operation Arrowhead in order to play DayZ again? Also, I got the game on steam account with my other games, but I would wish to have all the game on one steam account, so is there anyway for me to get rid of a banned game and get a new fresh one on a same account? Thanks in advance.
