Unknown column 'dc.type' in 'field list'

Okay, I've just updated to D7, and I've applied the core patch for drupal_alter(), but when I attempt to access Administration>Reports>Download Counts, I get a page with just this error:

PDOException: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'dc.type' in 'field list': SELECT dc.dcid AS dcid, dc.type AS type, dc.id AS id, f.filename AS filename, f.fid AS fid, f.filesize AS filesize, f.uri AS uri, COUNT(dc.dcid) AS count, MAX(dc.timestamp) AS last FROM {download_count} dc INNER JOIN {file_managed} f ON dc.fid = f.fid GROUP BY dc.type, dc.id, dc.fid ORDER BY count DESC; Array ( ) in download_count_view_page() (line 81 of /srv/www/[...]/http/sites/default/modules/download_count/includes/download_count.pages.inc).

Help?
