[Game] ARMA 2 problem? "Bad Serial Number"

[Mosin]

I know this is kind of random a TWI forum, but I just bought ARMA 2 to pass the time till RO2 comes out and I'm having a problem with it. I downloaded the Free version off Steam and played it and liked it so I bought the full game last night. When I finally tried booting up ARMA 2, it just showed me an error saying "Bad Serial Number Given in Setup." It never asked me for a serial number or anything that I can remember. However, whenever I boot up the free version (which works just fine) it does give me a CD key. I don't know if the free version is somehow making it to where I can't play ARMA 2 somehow. Anyone know how to fix this? Thanks in advance!

Run Steam as Administrator and check if that works.

Contact Steam. Often times they sell you games even if they do not have a CD key. I am guessing this might be your issue. It will take them a few days to a week to get it sorted out.

Thanks so much, that worked perfectly!
