Just a warning that I am getting:

user warning: Unknown column 'content_type_om_show.field_om_show_mpeg2_fid' in 'on clause' query: SELECT filename FROM files JOIN content_type_om_show ON content_type_om_show.field_om_show_mpeg2_fid = files.fid WHERE nid = 5 in C:\...\sites\all\modules\om_timeslot_scheduler\om_timeslot_scheduler.module on line 1089.

Nothing seems broken, just not needed any more?
