Ok thanks you guys, i will try your tricks! :)

Yes you are right but without steam launcher it didn't work...what means pmc, baf? i think that i don't have these DLC.... I donwload "sixwith" and apparently i can launch the game without steam launcher ... Karmaterror" i bought arma2+arma operation arrowhead + three extensions to have better quality as possible

when i launch arma 2 without steam, there is a message : "Bad serial number given in setup" but if i want play with dayz mod i must launch arma without steam....i don't understand why it doesn't work, i already reinstall the game :(

dulix, no i didn't do that, the problem come from this i think! Thank you for your link i gonna try this method

Thank you, i did this but he offer me to purchase arma two...however i have already the game...i had a mistake probably to buy the game on steam because nothing works :( when i want install new version he say me : "cannot find at least one of your arma2 directories"

Hello everyone, i bought the full edition of arma two on steam for playing dayz mod (i also download it on steam), but since yesterday i have too much problems and i can't play it. Firstly when i want to join a server the game say me that i don't have a good version and then my question is : Where could i procure the uptade of my version? Secondly when i find server with a compatible version(older version) the game say me that i don't valid the key for arma two operation, how i could done it on steam? Sorry for my bad english, i am french....if someone is able to help me i would appreciate! Have a good day :)
