Bad Serial Number Given At Start

[Fx_Rayz 0]

Today I was in a server and a hacker teleported me and everyone who else was in the game to a point and then from there i aborted. later that day when i tried to join the server i kept getting an error that said "Bad Serial Number Given At Start". why am i getting this? and how can i fix it?

start the game or steam as administrator (right click, properties, compatibility, put a check in run as administrator)

A hacker could not have done this. This is a problem on your end. A little Google-Fu says that you can try running the program as admin and verifying your cache via steam (i do not use steam so cannot verify if that is correct)

[AmberHelios 2071]

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 <-- this removes the cdkey from the reg

and do the same for arma2 oa

run arma2 to the menu <--- this puts the cd key in the reg so you get a clean insert

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
