I lost my ARMA 2 disc and i want to play again

[foamyrules72]

I bought ARMA 2 quite a while ago and i want to install it again to try out this DayZ mod i've heard about. the only problem is, i've lost my disc. i have a CD key, game manual and box but i cant remember what i did with the CD as i have moved since purchasing the game. is there anything i could do about this as i dont really have enough money to buy a game that i already have. thanks

Other than 1. finding the disc or 2. contacting the publisher of your version and seeing if they have a disc replacement service, there's nothing you can do besides buying a new one.
