QCube19 0 Posted July 27, 2014 Hello. As a lot of people have been having issues with the new 1.63 update of Arma 2 I've been getting my fair share of problem after problem after problem. I've abandoned DayZ Commander as it probably will be discontinued and got the new launcher via steam. I installed the mods I use as well as the update for Arma 2. After this, I tried to join the usual server and I get a request to delete a load of files and my server key was not accepted by this server error. Quick check on google suggests that the game is running vanilla and just needed to enable it in the expansions menu on the home screen in which I did. My game then crashed giving me the error...Data file too short 'C:\Program Files (86x)\Steam\steamapps\common\Arma 2 Operation Arrowhead\@DayZ_Epoch1051\addons\mbg_generic_african_buildings.pbo'. Epected 63480966 B, got 62986881 BI've seen this issue in the past and resolved it by heading over to steam and validating integrity of game cache... Which I done this for arma 2, OA, DayZ Mod and none of these worked at all. I even uninstalled all of them (Arma 2, Arma 2 OA and DayZ Mod) and reinstalled them back but I'm getting the same error. This isn't really a good thing when I spent 2 hours reinstalling looking for the problem.. PLEASE HELP!!! Share this post Link to post Share on other sites
