3.0.5588.1 - Sync Fails / Type Definitions Should Start with {

[jhoff80 87]

I haven't changed anything in days, but just noticed today my server is freaking out.  I get an error during sync, that also occurs when I try to browse the movie section of my collection.  My movie collection also now shows as empty, despite having the files and metadata still present in the folders.

looks like somehow you have some database corruption. you'll have to stop the server and delete your library.db file

That appears to have fixed it, thanks.

Just an FYI same thing here. And it started just after after the last update.
