Just a heads up to anyone interested: (Specially the CodeWeavers Staff)
I tried to play L4D2 in the new Steam UI, using, of course, the 9.0 Beta.
After skipping the Valve/Intro video, the game crashes, just like that.
No warinings, no flashes, no strange windows: It plain crashes.
Just to let you know.
I'm sure you are working hard on the new version, so, good luck!
