Component stopped working

[Bebrona]

I can't do the test because i can't create new category and reorder it.

The Back-end of the administratorpart to add Categories looks different for my website than for the testwebsite you provide.

Are you using abook 3.1.0 in joomla 3.4.3? If no I suggest to update them both.

[Bebrona]

I use abook 3.1.0 and joomla 3.4.3

Today i noticed my component was gone in backend.  So i tried to reinstall it. Then i got this error

Duplicate entry '1' for key 'PRIMARY' SQL=INSERT INTO `b9pwl_abcategories` (`id`, `asset_id`, `parent_id`, `lft`, `rgt`, `level`, `path`, `extension`, `title`, `alias`, `note`, `description`, `published`, `checked_out`, `checked_out_time`, `access`, `params`, `metadesc`, `metakey`, `metadata`, `created_user_id`, `created_time`, `modified_user_id`, `modified_time`, `hits`, `language`) VALUES (1, 0, 0, 0, 1, 0, '', 'system', 'ROOT', 'root', '', '', 1, 0, '0000-00-00 00:00:00', 1, '{}', '', '', '', 0, '2009-10-18 16:07:09', 0, '0000-00-00 00:00:00', 0, '*');
