I have uninstalled this plugin and all appears to have gone well. However when I come to create or edit a document I get a Database Failure.

The error message is

Mon Feb 6 14:52:27 2012 [8213][1][FATAL] Query Failed: Update documents set date_modified='2012-02-06 14:52:27', modified_user_id='1', created_by='1', description=null, deleted='0', assigned_user_id='1', document_name='WE Introductory Letter-2.doc', doc_id=null, doc_type='Sugar', doc_url=null, active_date='2012-02-06', exp_date=null, category_id='Marketing', subcategory_id='Marketing Collateral', status_id='Active', document_revision_id='20b6baaa-25d9-259d-ba77-4f2fcdea8e19', related_doc_id=null, related_doc_rev_id=null, is_template='1', template_type='mailmerge', google_docs_last_update_c=null, google_docs_is_spreadsheet_c=null, google_docs_id_c=null, google_docs_type_c=null, google_doc_last_command_c=null, google_docs_format_c=null WHERE ID = '1f55d03f-e0ae-9dbc-e832-4f2fcde08037': MySQL error 1054: Unknown column 'google_docs_last_update_c' in 'field list'

I have rebuilt relationships and repaired the database

My version is CE 6.31

It looks as if install has not happened fully - can anyone help?
