Thanx guys,
I think Jasper has a big attitude problem but thats fine with me.
I had this problem since last Christmas and have already contacted Nintendo about this, they said it was to complicated so the only thing i could do was to phone them.
Since then i have visited many fora without finding an answer.
Till now, i read you all of your support forum and stumbled across questions about formatting your WII(???).
I googled and finally decided to do it.
When i formatted my WII i could finally accept the internet agreement and everything works fine now....
