Komento crash at the installation

Hello, am french so sorry for my english.

I tried to install komento again after a crash of the database, and now when i load the archive joomla say :

1136 Column count doesn't match value count at row 1 SQL=INSERT INTO `jwovu_komento_acl` VALUES (null, '1', 'com_content', 'usergroup', '{\"read_comment\":true,\"read_stickies\":true,\"read_lovies\":true,\"add_comment\":true,\"like_comment\":false,\"report_comment\":false,\"share_comment\":true,\"reply_comment\":false,\"upload_attachment\":false,\"download_attachment\":true,\"edit_own_comment\":false,\"delete_own_comment\":false,\"delete_own_attachment\":false,\"author_edit_comment\":false,\"author_delete_comment\":false,\"author_publish_comment\":false,\"author_unpublish_comment\":false,\"author_stick_comment\":false,\"author_delete_attachment\":false,\"edit_all_comment\":false,\"delete_all_comment\":false,\"publish_all_comment\":false,\"unpublish_all_comment\":false,\"stick_all_comment\":false,\"delete_all_attachment\":false}')

what can i do ?
