Not letting on servers because of missing Serial key?

[grantupson 0]

So I just bought Arma 2 and all that on steam, installed it, but when I go to play Dayz on sixlauncher it says that I don't have a valid serial number registered? I tried going into Arma but it won't let me put any sort of serial in anywhere? Yet it still comes up with the serial I need to put in. If it helps I did forget to play arma before I installed and tried to play Dayz, any help would be appreciated.

Where did you buy it? You should be prompted to enter your key on install.

Also you need to run both Arma2 an OA individually first, that then combines them which is what you need to play DayZ.

I bought it on the Bohemia website but I bought it through steam on there.

Yeah, I ran DayZ first without knowing but I uninstalled that and I've gone in and played all of them now but I still have the same problem, it just won't let me in a serial key no matter what I do?

Edit; I have no trouble getting into the DayZ, but when I try and enter a server it says my product isn't registered with a valid serial so I can't actually get onto the servers.

alright mate

do the following and it will put the cd key in automatically for you

close steam

start steam in admin (right click and run as administrator)

right click on arma2 and properties then local files

click on verify integrity of game cache

and do the same for arma2 oa

run arma2 to the menu

run arma2 oa to the menu

click in expansions

make sure the following are enabled

arma2

arma2 oa

arma2 baf lite

arma2 pmc lite

if not enable them and restart then exit the game

then use your program of choice to update the beta and install dayz

and play :)
