Thanks for the help all.

Do not ever download anything from sites like that.
Just upgrade your game to R11 (http://goo.gl/d08WX) and place the dinput8.dll in your game folder.

But do i have to use original copy of the game or it can be used on Reloaded version too .. ?

Relaoded+latest patch=win win situation.

So i havent to use original copy of Bad Company 2 ?

Thank you .. cause i was thinking those 254 MB includе the Vietnam files .. so im not sure where can i find the Vietnam files, if you can help me about it ?

Thanks for feedback .. cause i did everything right ( i think ) with installation .. downloaded and installed the game from Origin .. install the patch 870 ( around 254 MB ) from noSTEAM site and put the 870 file in the game direction but when i try to start the game from Nexus icon game wont start ...

Hello there, wanted to ask can i play Vietnam ( nonbuyed ) with original copy of Bad Company 2 from Origin .. i mean i have already buyed Bad Company 2 from Origin but dont have Vietnam .. do i have to buy it too or there is anyway to patch the game like before and play it for free ?

n/a i get it.
