Ok that worked more or less the only problem is that in the next step it show a default fields in my case
Superuser
A Coruña
España
Telefono:
i would like those fields not to display because the people buying is a little stupid and i prefer them to choose add new adress and if they see the fields they must think is an error
The other thing is the required fields, that of course need to be activated...
it could be nice you can correct this option, it seems that for usability is very important as they told me to have a simple registration, wich i activated and the address inserted in the next step.
if there is a solution better if not hope you can implement it in next release.
