I just got ARMA2 COMBINED OPERATIONS today and i downloaded the dayz mod. i played both versions of the game before downloading the mod. I am using six launcher to run the mod and find the server when click on a server the first thing that pops up is " no entry 'expansion \dlta\product.bin.profilepathdefault". so i click "ok" and the game loads.Now this is the weird part my friends say they have never gotten this before the game loads up and it says "waiting for host" so about after 30 to 40 seconds this pops up "Files "c:\program files (x86\steam\steamapps\common\arma 2operation arrowhead\expansion\addons\warfare2.pbo", c:\program files (x86\steam\steamapps\common\arma 2operation arrowhead\expansion\addons\ warefare_e.pbo"c:\program files (x86\steam\steamapps\common\arma 2operation arrowhead\expansion\addons\ zargabad.pbo",c:\program files (x86\steam\steamapps\common\arma 2operation arrowhead\expansion\addons\ air3.pbo", c:\program files (x86\steam\steamapps\common\arma 2operation arrowhead\expansion\addons\animals.pbo",c:\program files (x86\steam\steamapps\common\arma 2\expansion\addons\ characters.pbo", ....are not signed by a key accepted by this server. to play on this server, remove listed files or install additional accepted keys." Then i hit ok and it shuts down i am running on the new update. please help me. for now i am going to re install Arma2 to see if it missed any files
