pitch shift not working

[aimeepink]

ive never had problems with pitch shift but all of a sudden it isnt working. I sometimes do covers of songs and i use pitch shift to raise or lower the instrumental into a key i can sing in. Ive always been able to do this. I select the whole audio and adjust the semitone and process but it doesnt change. Before i was having no problem and all of a sudden it stopped working. help please!!!

Is the "USe in Playlist" button highlighted on the plug-in ? If not, you might be writing the new files into the Clips List, but not replacing the original on the playlist.
