and another error message :

I've got the same problem.
Before that there is some graphic errors in HL2 menu (they are without background .... with a white line accross the diagonal of the screen).

My config: AMD64 3500+, K8Neo2, ATI X800pro, 1go ram
My error in the HL2 console:
Error: Material "console/background01" uses unknown shader "vmt"
Error: Material "vgui/friends/icon_away" uses unknown shader "vmt"
Error: Material "vgui/friends/icon_busy" uses unknown shader "vmt"
Error: Material "vgui/friends/icon_snooze" uses unknown shader "vmt"

My erro when i launch the game:
Map version is 0, expecting 19!!!
and crash.

*fixed*

I was having the same problem, here's what worked for me (copied from hl2fallout.com forums):

If you have the "Map Version is 0, expecting 19" crash, redownloading "source models.gfc" fixes it! It did for me.
