I had a quick look and the settings are held in three serilized wp-option entries, so you have a couple of ways, test this on a local install if you can.
1. change the theme while you do this, if you can run the database, run the wp-options table and delete three lines, ttw_options, ttw_myoptions and ttw_adminoptions, that should clear all values.
2. without running tables, add the code below to the functions.php of any other theme, lets use the "twenty ten" theme, de-activate the WP Weaver theme and activate the "twenty ten", this should delete the WP Weaver options.
delete_option('ttw_options');
delete_option('ttw_myoptions');
delete_option('ttw_adminoptions');
When you reactivate WP Weaver it will be a clean install.
