crash, first of all- Great images!
These look really good!.
The volume is not being displayed probably because of a BMP heavy wps. But if that were actually the case, then any image pre-loaded after vol_9 would not be displayed. Your progressbar would not be affected by the volume meter because it was preloaded a good ways before. Are your repeat and shuffle bmps showing?
As for displaying the Progressbar, i find that leaving height as an empty bracket works best and then defining x and y sort of through guess and check
works for me. (e.g. %pb||xguess|yguess|endpos|). If that doesnt work try switching them around a little. (I know its very unorthodox but it works for me).
