Album Artwork won't load error code -609

I was loading album art for a song, when I accidentally disconnected from the internet. Now every time I try to get artwork from the store I get the following message: "Artwork for XXX could not be found. An unknown error occured (-609)"

This error code refers to a connection error, but I'm able to get to the store and browse through to the albums I'm trying to get artwork for. I know I can do all this manually, but who wants to do that?

How can I resolve this error?
