im not sure what im doing wrong, i have the right iwi for the desert camo. i convert it to dds and open it in photoshop x32. i have an image i made and i drag the new one over the old one and delete the background. i save the dds as dx-t5 with mipmaps (ive tried dx-t1 with and without mipmaps as well) and the file size is the same. then i convert back to iwi and delete the last 4 bytes with hex editor. then i run the crcfixer with both locations and replace the file back in the mw2 main, and when i start the game it freezes and crashes to desktop at the main menu. can anyone offer some advice would be most appreciated.~smish
