need help with sound settings

[goducks]

Hey all, little help. Somehow I've got the settings screwed up for sounds, either from running SKtools or installing the Audiotweaks cab on the Haus's tips thread. Not sure which, but now when I go into Settings-> Sounds & Notifications -> Notifications, I can't set up my sounds anymore. My incoming text sound is there, but it won't play. My ring tone keeps defaulting to the one at the top of the list "Animato Tone." The sequence of events on this tab when I try and change sounds is:

I select the event and tone. I cannot preview sounds, I don't hear anything when I do.

I hit OK.

the phone thinks for a second, then resets to the first possible event "Incoming Call" and the first possible sound (Animato). And it never leaves the Sounds and Notifications page. Everytime I hit OK, it just keeps resetting like that.

I'm probably missing something obvious here.
