Horde calendar not working, after recent updates

[hodfords]

Hi, recently we've updated horde using upcp, from then on the horde calendar seems not working, all events gone, and when we are trying to new event, the following error comes out,

There was an error adding the event: DB Error: no such field : INSERT INTO kronolith_events (event_id, event_uid, event_creator_id, event_title, event_description, event_category, event_location, event_status, event_attendees, event_keywords, event_exceptions, event_modified, event_start, event_end, event_alarm, event_recurtype, calendar_id) VALUES .................[nativecode=1054 ** Unknown column 'event_creator_id' in 'field list']

it seems the db fields of kronolith_events is somewaht changed on the recent updates ...
could anyone please kindly help.

Thanks.
