Okay i changed some settings on my half-life 2 game and all i changed was the antializing part from 6x to 0 and so i pressed apply changes and it whent black then CTD and i get this when ever i try to start it up again i get a black screen like its going to go into the game but then it drops back down and i get this error message

Engine Error
failed to lock vertex buffer in CMeshDX8;:LockVertexBuffer

and then right after i click ok on that one i get this

hl2.exe - Application Error
The instruction at "0x241ebfb7" referenced memory at "0x0d8af41c". The memory could not be "read"

I got this message before and i'm trying to think how i got it fixed... hold on, i think

( hl2.exe - Application Error
The instruction at "0x241ebfb7" referenced memory at "0x0d8af41c". The memory could not be "read" )

This is where i found the solution... i think.

yeah but all i changed was the antializing from 6x to none why cant i just find the video config file and just change it back from there it would be alot more quicker and does anyone know where i can find the config file that contains the video settings?
