Why in certain styles when i try to load the style with user audio drums i cannot.It display an N on top of screen???

What OS are you running? If 4.1 or higher, did you save the style with the Audio drum from STYLE VIEW (after associating the Audio Drum with the style using F1, press SAVE)?

Im using version 4.1B.And i save with style view and button save like you said but if i save on style edit menu,it is the same problem.It happens on some styles i have. I dont know why.Another thing is that when i try to open the styles (with user audio drums included )in style compiler program it diaplays "bad styles" on loading.

??
