text module Update #6000 failed

Upgraded from drupal 5.7 (CCK 5.x-1.7) to 6.2 (CCK 6.x-1.0-alpha). All went well apart from a problem with text module Update #6000 .. here's some of the output:

Failed: UPDATE {node_field_instance} SET widget_module = 'text', widget_type = 'text_textfield' WHERE field_name = 'field_url' AND type_name = 'content_ot_courses'
Failed: UPDATE {node_field_instance} SET widget_module = 'text', widget_type = 'text_textfield' WHERE field_name = 'field_teaching_style' AND type_name = 'content_ot_courses'

(and it continues with each of the fields)

This was also outputted at the top of the update page:

user warning: Unknown column 'nf.active' in 'where clause' query: SELECT * FROM node_field_instance nfi JOIN node_field nf ON nfi.field_name = nf.field_name WHERE nf.active = 1 AND nfi.widget_active = 1 AND nfi.type_name = 'blog' ORDER BY nfi.weight ASC, nfi.label ASC in /home/willwade/public_html/otmatters/sites/all/modules/cck/includes/content.crud.inc on line 436.

.. and that continues too..

Should I be worried about this??!
