I am trying to re-install WPML on a site that had WPML installed a while ago. We thought we were going to translate it, decided against it and removed WPML. Now we are thinking of translating it. However, the database tables are not being created. The plugin components install and activate, but when the site crashes when I try access WPML, and when I go to phpMyAdmin, there are not database tables for WPML.
