no internal effects?

ive been using audacity for a year now and something went horribly wrong. i lost all my internal effects. i reallllllllllyyyyyyyyy need them back. i tried deleting amy audacity.app, then reinstalling and that didnt work. HELP :imp: :smiling_imp:

Ordinarily, reinstalling would be a delightful thing to do…except in Audacity. To “reinstall” audacity, you have to change a Preference file and leave Audacity.app where it is.
