[mysterio2]

the other day out of the blue all of my sound files jus up and became corrupt and wont play for my ringtones and they wont play in my windows media player in fact it wont even open up any more what can i do to fix this problem ive already tried removing all the files and putting them bac on there but they still dont seem to want to work

you could sync your contacts and hard reset. i was going to suggest deleting your tones and replacing them to see if that worked but since you did try that and that didnt work, maybe it isnt the sound files but maybe the sound application?
