Languages not appearing on Registration page

I followed the instructions and installed Sign Up Language but first copying the .mo files to languages folder and uploading to wp-content then of course uploading signup-language.php to mu-plugins

On new user sign up the Languages do not appear on the registration page. This is a default WP registration.

Per instructions...

just drop a heap of language files into /wp-content/languages/ and then let your users select which one they want to use at signup!

When I check the tables I only see...

FROM wp_signup_language
LIMIT 0 , 30

But from sql.txt it should look like this...

CREATE TABLE wp_signup_language (
language_ID bigint(20) unsigned NOT NULL auto_increment,
language_blog_domain varchar(255) NOT NULL,
language_blog_path varchar(255) NOT NULL,
language_value varchar(255) NOT NULL default '0',
PRIMARY KEY (language_ID)

Unless I am not sure how to find the rest of the entries.

Help appreciated before I go overwriting my db tables
