robin.lindstrom@live.se 0 Posted June 19, 2012 This game has been working fine with arma free + operation arrowhead, but yesterday i bought arma 2 (both for supporting the devs and getting nicer graphics) but since then ive been getting the error "Invalid GUID" and battle eye kicks me.Both arma 2 and operation arrowhead works fine on its own.Its only on DayZ servers this is happening on, as far as i know.Ive updated battle eye several times, reinstalled dayZ and im using six launcher. Not sure what im doing wrong, please help!Edit, arma 2 is from steam, operation arrowhead is from retailer download (greenman gaming) Share this post Link to post Share on other sites
