Thanks, I tried that, but it didn't work. It doesn't seem to matter whether I click on the MAT pose file or try through the 'Render materials' box, it just either tells me the file is not found and asks me if I want to continue looking for missing files (which also doesn't help), or simply does not add the bump map to the list. I'm not sure if it the problem lies with the MATs, Poser or me!
