Error 11556
This alert occurs when iTunes is trying to do something not allowed by the iTunes Store in that country.
The most common example of this is trying to sign in while limited to iTunes U by Parental Controls.

I followed the steps that you gave to me, but it's still not working. But what do you mean with the first thing you said?

The two links are to the same support article in English and Dutch. Everything after is a quote from the English version related to that error number.
I've not personally run into the error myself but it would suggest that it may be related to parental restrictions. Are any of these turned on?
