You are too fast, so this gets out of sync... :-) Just thought of one more reason... 4) Very often creators decide to post the bump template rather than the converted .bum (because it compresses much better), so there will be a "something.jpg" or "something.bmp" instead of the "something.bum" which is referenced by a .cr2. This can't be directly handled by the converter/installer, but it is the reason which brought me to write the GraphicConverter filters - just open "something.jpg" in GraphicConverter, run the "Poser4" filter and then save it (selecting ".BUM (Poser)" as format) before you install it - that's it.
