HTC Desire :: Can't Select Normal Ringtones For Notification Sounds

so I was clearing up some room for a new app and went through managing apps and deleting some and clearing some caches. And now, I can't select any of the normal ringtones on the phone for my notification sounds. When I go Personalize > Default ringtone > select ringtone. It comes up saying 'Phone Ringtone' With options of OK and Cancel. It gives me no choice of any of the old normal tones the phone had before....what the hell is going on. Same for text noises btw.
