I have a problem with cydia. Cydia was working since yesterday after i jailbreak with blackra1n at 3.1.2.

But just about an hour ago i tried opening up Cydia and i get some errors and all my sources/packages ARE GONE!!!

It says cache Failure when i start up then a message box...

Error: Refreshing Data
Failure to fetch

and at the bottom of the message window it says

Some index files failed to download,
they have been ignored, or old ones used instead...

I also noticed on the cydia home screen the
"3.1 shsh has been signed," has disappeared

anyone with a solution to this,,,I dont have ssh installed
