Steam log

After updating yesturday, Portal 2 crashes at loading level.

I installed Steam in Wine 1.2-rc2 and Portal 2 crashes at the menu. After this
I have been update Wine to 1.4-rc4 version. To run Portal 2, I disable
"gameoverlayrenderer" in this two versions of Wine. I don't install DirectX,
.NET and vcrun - Portal 2 works fine one or two weeks without it.

Yesturday Steam was download an update. Afret installing it, Portal 2 become
unplayable because of crashing at loading level. I can browse menu and watch
videos. But I can not load all saved games.

Steam version: 1818. I can't check other Steam games.
