I can only give general information/advice.
Generally speaking the PA addon was bug free, except for inherent SH2 bugs which could not be removed because they were hard cored ( like the "save game" bug)
Problems are nearly always traceable to an incorrect install procedure or unsupported option settings. The full correct install of PA does have several opportunities for getting it wrong .
Yes, there is a german spy on board. I believe there were a couple of original sound files that were not replaced.
Could you provide the following :-
Which install are you using ?( full or lite)
What is your exact install sequence ?
