Can not edit the adresses in user menu

Hello,

I have a strange problem. I copied all the data-tables from hikashop from the joomla 1.5 to the 2.5 installation. It seems that all works fine now and I could go online with the new site. But after some tests I have some problems. When I login into the site and go to the user menu then there is an option to edit the saved adresses for me. But if I klick this and want to change my address than there is nothing showed and it says that I should login, but I am allready logged in.

AND, the menu "Entries registration" shows nothing.....

Please help me so that I could go online with the new site.

Thanks!

Regards, Benny.
