Problems with user registration, "field is required" errors

[komiko]

Hi , I am having many errors with the required fields when a new user is registering, even when they complete all the fields.
 

This is what I am getting when I submit the form:

There is 7 Error(s):

• Country cannot be loaded with address->id_country
• Country is invalid
• id_country is required.
• lastname is required.
• firstname is required.
• address1 is required.
• city is required.
