Metal Gear Solid 2 Substance Bug

I was playing the Plant part of the game and got to Strut D. Now, the problem is, when I took out the guard who did a radio check every few dozen seconds the enemy as usual came to investigate. After they woke up the guard I took out with the M9 I heard a brief radio sound and no one said anything, plus I was unable to use my Codec after that. When I left Strut D the screen froze on "CD Connecting Bridge". This is a problem because I collect dog tags and there is no way for me to progress with this bug. I would appreciate help please. Should I reinstall the game, change sound or hardware acceleration?

Hey i was also facing da same problm until i found a solution to it.I was facing this problem at every connecting bridge.

If u disable the Pixel & Shader of ur graphic card then it wud surely fix ur problem.

Do it and then tell me abt it ok.

guys its been a long time since a played mgs2, anyone know's if it works with vista or any patch available? thanks1407

No goes with Vista, and they have patches for ATI and Nvidia cards that should fix the shader issue

"they have patches for ATI and Nvidia cards that should fix the shader issue"

I tried every Ati and Geforce patch but they didnt solve this issue.These patches can fix the graphical corruption but fail to fix da mentioned problm.So i manually disabled da Pixel & Shader.
