When I try to run the My Files, My Photos or My Music apps, I get this message, and then can't see files or music or photos.
The phone is rooted, but the only thing I've done with it is to install Titanium B/U and freeze some of the bloatware.
Zumoservice is listed under the backup/restore tab, and it's not frozen.

I don't know what I did here. It was working after rooting. Is there a way to manually start it?
