Unable to remove / un-install Forum die to conflict with Field SQL Storage database table

Hi,

I am trying to uninstall the 'Forum' module but I am getting the following error:

PDOException: SQLSTATE[42P01]: Undefined table: 7 ERROR: relation "field_deleted_data_245" does not exist LINE 3: field_deleted_data_245 field_deleted_data_2450 ^: SELECT DISTINCT field_deleted_data_2450.entity_type AS entity_type, field_deleted_data_2450.entity_id AS entity_id, field_deleted_data_2450.revision_id AS revision_id, field_deleted_data_2450.bundle AS bundle FROM {field_deleted_data_245} field_deleted_data_2450 WHERE (field_deleted_data_2450.deleted = :db_condition_placeholder_0) AND (field_deleted_data_2450.bundle = :db_condition_placeholder_1) LIMIT 10 OFFSET 0; Array ( [:db_condition_placeholder_0] => 1 [:db_condition_placeholder_1] => article ) in field_sql_storage_field_storage_query() (line 582 of /var/www/htdocs/modules/field/modules/field_sql_storage/field_sql_storage.module).

This seem related to the Field SQL Storage module, but I couldnt find the problem:
- The above named db table does not exist in the database, however very similar ones do (field_deleted_data_258, field_deleted_data_41, field_deleted_revision_258, field_deleted_revision_41).
- These similar tables seem to get created when I enable the 'Forum' module, but they do not get deleted when I try to uninstall it.
- I could not find any reference in the Forum or the Field SQL Storage modules re this table.

Any help is greatly appreciated.

Thanks
