When you disable the module in the modules section and then reenable it, the blocks that the module has created have lost their region (have gotten region ) so are not visible anymore and need to be reconnected to a region on the blocks overview page.
Disabling and reanabling a module should not make any changes to a site because this is the recommended workflow when upgrading an installation.

Anonymous (not verified) commentedThis module is no longer being actively developed as it duplicates functionality that can be obtained through the usage of taxonomy_menu ( http://drupal.org/project/taxonomy_menu ) and dhtml_menu ( http://drupal.org/project/dhtml_menu ).
