Media Card encrypted on another device..

After updating from 10.1 to 10.2, my media card no longer works. Says it's encrypted on another device, when I never used it on any other device. It's asking that I reformat it.

I know, you're supposed to back everything up before updating. My mistake. I have a lot of pictures on my media card from my trips. Tell me there's a way to salvage them..

I searched these forums and the BlackBerry forums, but I haven't had a satisfying answer. I fear the worst
