"Cannot open bin.pbo" error...

[SogoProds 0]

Hello guys i'm SogoProds and i have a problem.Recently i obtained ArmA 2 Combined Operations so i can play i can play DayZ.Everything went well:i installtled and updated both ArmA 2 and DayZ thruogh DayZ Commander.Everything i ready and when i tried to connect to a random server this happend:

 

ArmA 2 OA

 

Cannot open file E:\Games\ArmA 2\\dta\bin.pbo

 

I read about this problem and everyone said that i must go to regedit to remove a backslash from the directory of the exe.I did.Twice as a matter of fact.And nothing.DayZ still doesn't want to start.

 

There were some more solutions like puting this "-mod=dayz -nosplash" in the name of the arma 2 oa.exe.Same thing.DayZ still doesn't want to start.

 

Other say that i must first run "arma 2.exe" and then run "arma 2 OA.exe" and then try to connect to a server.The problem is i can't open arma 2 OA.First a error appears saying:

 

ArmA 2 OA

 

No entry 'bin\config.bin/CfgInGameUI/MPTable.shadow'.

 

And then another one saying:

 

Error compiling pixel shader PSSpecularAlpha:0.

 

I can't find more advices and i hope someone here will help me.

 

PS.:I'm sorry for my grammar.
