update v. 5.1: fix a bug for php5 users: this built-in SOAP extension used same soapclient() class name as Nusoap. I just change the class name in sopclient_nusoap() in the files nusoap.php and validations.php both in admin and catalog.
Have a look to http://fr2.php.net/manual/en/ref.soap.php for more infos.
Also add 2 more countries (Bulgaria and Romania) in the EU countries array (thanks to Madenio).

FULL PACKAGE

For version 5 users, just replace classes/nusoap.php and functions/validations.php files in both admin and catalog sections
