youtube favrites sudenly not showing up in mediabar?

Since last week my favrites haven't been showing up in my flock mediabar however all my other streams such as photo's show up as normal this is rather anoying as I used this feature alot. here the error message I get " there was an error in proccessing your reqeust. Please try again. if this persist try restarting flock" I restart flock but it makes no difference.
