Texture Modding Problems

Hey guys,
i've recently just tried modding, and im not really the person to ask for help
but i've tried jorndel's modding tut and did exactly what he did and keep
getting couldn't load image
can any1 help please?

first open photoshop (admin), then open dds trough photoshop( i had same problem on windows 7 x64)

Can't load the image in game, or in photoshop like above said? Because for photoshop, you need to run photoshop in 32 bit mode for it to work, and if its the game, you need to make sure you saved it right.

It's in game

Make sure you are saving the file right. It needs to be in the right format, and MIPmaps need to be generated or not depending on the file. Also make sure you are doing the hex editing and CRC fixing right. Use IWIfix to help out with that.

I don't really understand HEX, are there any tutorials??

NVM, i figured it out, and am making All secondaries gold, releasing soon!
