[abbasbidi]

I'll just get right to the point.i can't install the game after i uninstall the game for mods that add to game.i played easily before and decided to reinstall it.i use copy version that is 3dvd i know that it's not my game problem because i played before that uninstall it.
my error is
Wrong disc inserted.
Please insert the original "ARMA2OA ANNIVERSARY EDITION" CD/DVD.
Please have a look at http://www.securom.com/message.asp?m=wrongdisc for further, more detailed information.
