(adsbygoogle = window.adsbygoogle || []).push({}); I download black rain patch and it works great but I can't find people online anyone know why ?

Because you're obviously playing on bypass.

Ohh I am so confuse what bypass and all that thing work for

You're bypassing the 1.14 game update by using the 1.11 patch. So you're playing Mw2 on the 1.11 game update which is not used anymore.
