I think it means that the structure of the website changed and that the websource script is no longer compatible, but I am not 100% sure.

Edit: It can also mean that the website failed to reply in the given time. Try increasing the timeout to 15 or something higher in the options.

Not working...

You might wanna tell the world what exactly you did to evoke this message.

I think it happens when the freedb-id calculation produces an id that does not exist in the database.
This can happen if the selected files are not in same order as on the album or just of incomplete number.
