Кстати вот оф текст с сайта zBlock'а
Counter-Strike: Source has been updated to the Orange Box Engine and this update made the latest zBlock Version 4.4 incompatible to the new engine.

But we are working to get zBlock back inGame.

We require time to make changes to our beta version of the plugin so that it will function correctly with this release.

This will essentially be zBlock 4.4 with our DeadVoice Plugin and the latest CrashBlock integrated. From then we will add features which are present in our version 4.5 release.

The development has been slowed because of SDK omissions and the need to change the internals because of differences on the new engine.
Parts of zBlock have been completely rewritten and need to be fully completed and then tested before we can release a beta version.

zBlock 4.5 will only support CS:S, but more games will follow afterwards.

A different note to you:
We would like to move your attention to something different. Our servers are very busy to serve a competitive and fair playing field everyday and everynight for YOU.

ps Кстати, когда WikiPedia обомжела, а если серьезно у нее не было денег на оплату работ программистов, они просили донат у юзеров с сайта. Но добрые Google спохватились, и за не много денег купили доверия. Почти за 8 000 000$. Хороший взнос.z
