Upgraded to business, and now to joomla 2.5

All seems to have gone swimmingly so far, followed the instructions on this forum about upgrading and moving tables, and magically my ecommerce appears!

I have a slight problem that I cant get my head around. I am getting the message 'Please create or select an address' which I didnt get before in the cart section.

I have login, address,cart,status,fields in the checkout flow, I have registration selected and login Yes.

No sure what I have done wrong, is there something missing I have not done ?

Joomla 2.5.4, Hikashop business. Test server at redcell.co.uk/oceansafety at the moment.

hmm, my admin account always had an address associated with it, very confused.

I have my Joomla 1.5 site sitll running at oceansafety.com and all is good, admin can login , it displays the address details for him and it moves on, but on the Joomla 2.5.4 site, it just gives me that error.

They are both running business edition of hikashop ofc
