The latest Service Pack update changed the access structure for ringtones.

I have lost access to all of the custom alarms, notifications and ringtones I've made and/or downloaded. I can see them all still in the original folders when using a file explorer, so I know that they all remain on the phone, but what changed in the access structure? What new folder do I need to move them to in order to regain access ?? I tried moving them to the Music folder, but they still don't show up. The custom ringtones I assigned to individual contacts have even been reset to a default, very frustrating.
