Neutron2

Hey all, i'm new here, and new to ArmA2. Last week I bought ArmA2 at a BestBuy, getting pumped for this game(and the soon to be Project Reality mod). Long story short- after many many hours of downloading and installing(and being out at dinner while it installed) I got home and found that it had an error something like 'wheel2.pbo was not found' Or something very close along those lines. I clicked okay and the whole downloading went ka-put. Ive retried downloading/installing ArmA2 3 times since my original attempt, and everything I have the same error message. Someone said I should go to Steam and type in my access code to get the game from Steam- but that didn't appear to work-no matter how many times I put the code in(also, there is no manual in my version of the game, just a 2nd CD as the manual, and a sticker which I assume is the CD code) What can I do to play this game :/? If I need to post my Supposedcode to get an answer then I will. I just want to be able to play this game! Thank you for your help -'Neutron'

Alright, well I've messed up a LOT with my computer lately. Please tell me how to do this.

Alright. I exchanged my copy of ArmA2 at BestBuy and got a new one. Still won't work. Is there any legal way to get an online copy? My computer won't read the disk and the last disk was devective. I bought a legitimate copy from BestBuy and am willing to show the recept, exchange recept(from today) and CD copy. Someone please tell me if there's anything I can do! Bestbuy won't accept returns and I don't want to spend $50 on an online copy when I already spent money on a hard copy i'm holding in my hands!

Something is also wrong with my computer apparently. I just inserted the disk and nothing happened. So I went to MyComputer and clicked on the drive the disk was in, the disk ejected and a message popped up and said, "please insert a disk" .....Anyways- I still have the problem with ArmA2 stopping the "extraction/installation" when its SO NEARLY done, then nothing happening. Any help there?
