EquinoxME 0 Posted July 21, 2012 okay, i was hoping on getting DayZ working on my computer. I downloaded Arma2 free from the offical website. then bought operation arrowhead from Gamesrocket.com.i looked at someone named kodabars (or somthing like that) install guide for DayZ and one of the steps for the non steam install was to run both: Arma2 free and OA after install.arma2 free works and startsup fine, however when i try Operation Arrowhead i get an error code saying."Data file too short C:\program files\bohemia interactive\Arma 2 Operation Arrowhead\expansion\addons\ui.pbo. expected 31968514 b, got 1233977"im not the smartest guy but i know i messed up somewhere. i do know that another step before was to copy the addons folder from arma 2 free to Operation arrowhead. while doing this i got another error code saying.."cannot copy sound: data error (cyclic redundancy check)."So if anyone could talk me through what i did wrong i would be entirely happy.it might also help to let you know i have used the six updater for DayZ and i am confused on the step with beta patching. so please help if you can. :D Share this post Link to post Share on other sites
