Custom fields do not saved after registration

Hi Marco,
first of all thanks for your useful plugin.
I go to explain my problem: after i send the form registration (in it there some custom fields) an email arrive to me with the registration confirm, then i click on the link but the target page is blank.
After that i go in the list of users (Cms area) and i can see my new user but all custom fields are blank.
Otherwise I can login with no problem in wordpress cms area.

The web site is http://www.cias.it
Can you help me? If you need other informations, please ask me.

Thanks in advance!!

Andrea
