Source SDK 2007 Download problems

I download the game, and when i click to play, the download window of the source sdk 2007 appears, the problem is that when i try to download it, steam close up without tell me a error or something.

I scan the computer for virures with avira, i reinstall steam, and the game, i restar the computer a nothing… somebody can help me because i really want to play :c

Maybe try downloading Source SDK Base 2007 manually from under the “Tools” section of the Library?

Can you download other games normally? or is it only With source SDK? If it’s with everything try reinstalling steam and cleaning your registry with Ccleaner or similar

OOOO-Kaaaaaayyyyyyy. . .
Tools section?
Library?

Pleeease, somebody, tell me how to “download and install” Source SDK 2007!:’(

In steam you have your library menu. Change section from “All games” to “tools”.
