[Plugin: NextGEN Gallery] Will not install correctly

I’m having major issues trying to install NextGen Gallery v1.82. I’ve tried to manually and automaticlly install the plugin, but the tables in the database never gets created.

WordPress v3.2.1
PHP v5.3.6
MySQL v5.5.14

The steps i take to install NextGen;

1. Plugins > Add New > search for NextGen > click install now.

Downloading install package from http://downloads.wordpress.org/plugin/nextgen-gallery.zip…

Unpacking the package…

Installing the plugin…

Successfully installed the plugin NextGEN Gallery 1.8.2.

2. Click the activate plugin button
Plugin activated.

3. When i expand the gallery section i only have 3 menus, Tags, Roles, Reset / Uninstall. But all of the 3 menu options point to the …/wp-admin page.

4. When i look in my mySQL database i only see these tables.

+------------------------+
| Tables_in_xxxxxxxxxxxx |
+------------------------+
| wp_commentmeta         |
| wp_comments            |
| wp_links               |
| wp_options             |
| wp_postmeta            |
| wp_posts               |
| wp_sticky              |
| wp_term_relationships  |
| wp_term_taxonomy       |
| wp_terms               |
| wp_usermeta            |
| wp_users               |
+------------------------+

Am i missing a key php extension?

Is there a way of removing all traces of NextGen? I have tried deleting the plugin and reinstalling it but it will not setup the tables.
