.dds injecting problems

[Shdw Shinobi]

I'm using DOThalo and Photoshop to inject bitmaps. I can do the warthog just fine, but when i move onto other objects, it says i need a DXT2/DXT3 file. When i export from photoshop, i use DXT3 of the .dds format. Then i tried doing this through DXTbmp, and it would inject, but the bitmap would be all messed up, and pixelated. Does anyone know what i'm doing wrong?
