Working Plugin for Massive AddressBook Importing for latest release

Good morning,

I am so sorry to write that... but really I didn't get it out. I looked in the group and discussion but I was not able to find a solution. I have to import around 500 users with the following fields:

username, password, name, surname, company, role, email, mobile, mobile2, notefield


but no one of the plugin I tried it is working with the latest 2 releases. Can you please give me a tip?
