How do I downgrade to 1.0004 patch?

[McJiggy]

I'm trying to install the Amk 1.4 mod but I need to change the patch but can't figure it out. even with the google results I look up. Is there a fast and easy way to do this?

Autumn aurora 2.1 needed it also, But I could play it with the newest version.

When I try to install the 1.0004 patch by extracting it into the stalker folder the game won't even start when I try to and I have to verify cache to get it to work again but that puts the game back to thhe 1.0006 patch.

How do I get the 1.0004 patch to work without it making my game unable to start?

run the patch (1.0004), it will install to a folder THQ! just coptyand paste file into your Stalker directory, it should work afaik! just remembered you will need to make a few registry entries. just do a search on youtube about stalker patch downgrade, there are a few videos that show you how to do this.
