DDS Texture problem!

Hi everybody,
I'll go straight to the point:
I'm trying to mod a game's textures, I succesfully exported them but when I edit them with paint.net, doesn't matter how many colors I put, they all become black. If I draw a big white circle, it will become black in the game, and I don't know how to fix this.
Also, if it could be useful, I tried all DXT formats, and each of them with the same result. I guess it's a shader problem, but I don't know how to add colors to it.
Thank you for reading.

Did you try using GIMP? I never had any problems editing dds files with it.

Thanks for your reply, but I actually don't have any problem either in modifying them,
it's just that the colors won't show up in game.
Also I'm running Windows, so there's no way I can run Gimp.
