Counter Strike Source : the server requires that you be running steam. [CLOSED]

Hi,
I've downloaded the games4theworld Counter Strike Source version and been playing it for almost a week without ever noticing the slightest problem. Come this morning, I've started getting this message every time I try to connect to a server : "the server requires that you be running steam"



I never had Steam installed on my Pc, I did not temper with the installation files either. I deleted it, reinstalled, updated anew but nothing seems to be working.

I even installed Steam, but in this latter case, the game refuses simply to launch.

Any help or suggestion will be welcome, I've searched Google for hours and now I'm at a loss for alternatives.

Thank you, and good evening.
PS : I apologize if this is not the right section to post in, I took the first Counter-Strike-Source-Problem-Topic I found and posted in the same section
