For example, these are the MAT files from DAZ for V3. I used MPE's batch process utility to change these MAT Pose files, then I changed the names of the original PNG files to match. I still have some concerns about exactly what you're doing. It appears you're trying to edit MAT Pose files within Poser 5, which you should not try. Also I couldn't seem to find any hair with Bump maps. But I don't have the hair you mentioned. I'm in the process of reinstalling all my software and reorganizing my office. I don't mind taking time to try and help, but need to feel you're "hearing me."
