What is the best settings to use for a: HP Pavillion G6 Series 8GB of Ram. i5 processor Windows 7

I purchased them on steam and bought a new PC so, I did everything I did on my old Pc but it said, Old setup Key?

Hi, I recently went to start up my new Arma 2: DayZ Mod which I just installed on my new PC and it had told me I have a bad setup key? Any help would be perfect, Thanks. I asked Steam Support and they directed me here so anything may be an advancement. I am not very good with technology therefore don't be sending me with massive instructions to follow, Break it down and make it simple please. Thanks for anything you can do.
