Hi there, i downloaded the latest beta patch [my first time trying beta] from here. I installed the patch correctly. It created a shortcut in this folder "D:\Games\Steam\SteamApps\common\arma 2 operation arrowhead" called "Launch Arma2 OA Beta Patch". If i start this executable i get this error message "addon dayz_code requires addon cabuildingparts". So i thought i have to add some parameters to start Combined Operations and not only OA. I tried out these instruction given in this forum http://dayzmod.com/forum/showthread.php?tid=9314. Now i get no errors anyway but if i join a server i can only see the ground and some people standing around. I made a screen hope you can help me Screen: http://s1.directupload.net/file/d/2923/p7vhjm4c_jpg.htm Dunno why theres a guy standing in this "nirvana"

with that patch i only see the ground ingame. no vegetations or anything :[
