Error when creating nodes, after adding to Newsletter lists

Hi, I apologise if this has been dealt with elsewhere, but i've searched and found no solution.

After adding two more lists to the standard Newsletter list, all attempts to add a node resulted in the below error:

PDOException: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'target_id_tids' in 'where clause': SELECT * FROM {field_data_field_newsletter_list} WHERE field_newsletter_list_target_id = :lid AND target_id_tids IS NOT NULL; Array ( [:lid] => 2 ) in NewsletterAutomated->getNodes() (line 131 of ..../sites/all/modules/newsletter/includes/newsletter.automated.inc).

Only after deleteing the lists I had added, was I able to node/add stuff as before.

Would appreciate any help with this as the various lists are real important to my project.

Thanks!
