Updated my os ringtone problem

I updated my os today and two of my custom ringtones will not play. They are now listed as only one sec. long and nothing plays. When I went to the desktop manager and pull them up on my media card it says that can not be opened and need a program to open them with any suggestions?

Weird. I've had to reestablish them via Profiles/Advanced from a copy I had stored on my SDmicro card but I've never had a file format change on me during as OS upgrade.

They now are .rim files and I can't change them back
