I've been trying to connect to the (Pal) E-shop for a while now today and all I ever get is this one error code, Anyone else having similar problems? All I'm told to do is turn my 3DS off and on again and that doesn't do anything at all. =\
Oh, I see, I'd guess that a quick google search lead other Europeans to this site? Guess we're all getting same weird error code, Glad to know it's not just a problem on my end, All I can do is try again some other time. =P
I had the same problem (the day where the new Club Nintendo games were available) and I learned later it was because my Internet distributor had problems.
