audiosuite plugins dont work!!!

all of a sudden none of my audiosuite plugins work any more.. I try and process but the file never changes.. I can even undo them but the file never changed to begin with.. I open a plugin, and process but nothing... please help!!!!

I had a similar situation happen, and it drove me nuts! Until I realized that I needed to activate the "use in playlist" button. This processes the track you have selected, and replaces the original with the processed audio. You may have already tried this, and if so I apologize for the post. If not, give it a go, I think this may be your problem. Good Luck.

THANK YOU!!!!!!!!!!!!!!!! it worked
