Cannot Upload Files

Hi, We came across a problem with the file uploading of the LMS. Once uploaded, an error page is generated. According to the logs, this error came about: PDOException: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'lms1_4.field_data_tft_file' doesn't exist: SELECT f.filemime, f.filename, v.title, n.changed, n.uid FROM {node_revision} v LEFT JOIN {node} n ON n.vid = v.vid LEFT JOIN field_data_tft_file c ON c.revision_id = v.vid LEFT JOIN {file_managed} f ON c.tft_file_fid = f.fid WHERE n.nid = :nid AND n.status = 1; Array ( [:nid] => 326 ) in tft_get_content() (line 697 of /var/www/profiles/opigno_lms/modules/opigno/tft/tft.module). To add as well, I also tried to add a file field onto the slide, to compensate for this error. What happens is that if a user creates a new slide, and attaches a file onto it, the slide does not register onto the lesson. Requesting assistance on these matters. Thanks!
