Sources not working

Recently, when I want to add books, it says: nothing found (even when I try it with books I've added before, so I know they were there in the past). This happens with Koninklijke Bibliotheek (NL).
Also, when I want to add books using the option Bol/Bruna, I get this error:
Warning: simplexml_load_file(): http://athena.librarything.com/api/dutch.php?search=aan+de+bal:9: parser error : Extra content at the end of the document in /var/www/html/inc_externalbooksearch.php on line 43 Warning: simplexml_load_file():

The used table type doesn't support FULLTEXT indexes
in /var/www/html/inc_externalbooksearch.php on line 43 Warning: simplexml_load_file(): ^ in /var/www/html/inc_externalbooksearch.php on line 43

Please, solve this soon, I need to add all my school's books, and time is running out
Thanks

There is a known problem with KB. Check this thread.

If time is such an issue, you might want to use "Vlaamse Centrale Catalogus" as source.
