I just tried. It says "no update available at the moment".
I was doing the first update (without message) yesterday right after I saw Soriku's thread about the WiiWare update message. I did not find a message on my Wii, but this update. About 15 min. after this 1st update I got the message saying that the WiiWare update now available and I did the 2nd update.
Maybe Europe got these two updates the other way round than NA.
