Look, this is not that kind of forum. We try to edit the files of the game to make mods or translation.
Your DVD or the files are corrupted. Donwload it again or go to the store and buy it if it is a warez copy.

Upload an unhandled dxt5 file, because your program works fine with Tosyk's f01c.texture file, which is a dxt5 file.

Go to the store and buy it. Problem solved.

If you deleted the first 84 byte from the beginning of the .texture, just paste the first 128 byte from the dds to the beginning of the .texture.

The .texture header is 84 byte big (54h). If you delete exactly this part, no more or less, the color will be ok.

There is you file, f01c.texture. If you open it to read in hex view (or with hex editor), left side you can see a counter. These are the offset values. At the offset 38(hex) begin the width and the height data.

Which part?

If the color is wrong, you leaved some non-image data after the header, and the image data is shifted. Or if you deleted too much data.

Image size:
offset38: 4byte width, 4byte height (00080000 00020000)

You used wrong DDS header, and the dimensions are also wrong.

Create a dds file with 2048x512 dimensions, and DXT5 No mipmap compression, and paste the header.

It seems, this game use the engine of Fahrenheit/Indigo Prophecy (of course upgraded newer version) or just the structure is very similar; Unicode text with ASCII ID, and DDS textures.

This is soooo easy: rename to zip! But encrypted.

Zlbi compressed. So not a big deal.

Why is this rush? You can't wait at least a day to the answer?!
Tomorrow I'll try to upload the files what you need.

Maybe I can help you. Which language?
By the way, if you dowload the cod4 ModTools (~1GB), you can find there the subtitle files.
