The black parts are probably bad vertices, if you load the object file(se) into UV Mapper and hit the insert key it will fix any it finds. However, if there are too many it will often crash at this point! If it finds any you will have to resave the file and delete the .rsr file, of course. As to the CR2, gloves like this might have to start from the forearm, especially if you wand them to bend here (but looking at it, you might not want a bend). If you need forearms you may be able to have them as a phantom part, not actually in the object file.
