Arma 2 Field Manual

[MartinE-Z]

Hi I dont know exactly where to go to post this and I am sure this is not the place to ask but I cannot find anywhere else. Well last night I got trojaned and I had to reformat and as you know with reformats all is lost and with that I cannot find my manual for the cd key. I play arma 2 and am in a tac. realism unit and I do have it installed on my laptop but I would like to get it installed back on my desktop as my desktop is better qualified to handle the game. I just want to know if there is anyway I can get it back on my desktop without having to purchase a new one if there please email me with help as I know this is information not suited for an open forum.
