i just bought a brand new computer with windows vista home premium and
Counter Strike Source, installed it and when i run it, it starts
updating and at about 25% the following message appears:

Debug Assertion Failed

Program: C:/Program Files/Steam/Steam.exe
File: /p4clients/rel_beta/Projects/Common/Misc/Win32Registry.cpp
Line: 447
bCloseRet == 0L
(Press Retry to Debug the Application - JIT debugging must be enabled)

What is JIT? How can I enable it?
