Joomla 1.5 (legacy on)
JEvents v1.5.2

This is all that appears on Manage iCAL Events:

Table 'joomla2.jos_jevents_vevent' doesn't exist SQL=SELECT count(*) FROM (jos_jevents_vevent AS ev , jos_jevents_icsfile as icsf ) LEFT JOIN jos_jevents_rrule as rr ON rr.eventid = ev.ev_id WHERE icsf.ics_id = ev.icsid AND icsf.state=1DB function failed with error number 1146
Table 'joomla2.jos_jevents_vevent' doesn't exist SQL=SELECT ev.*, ev.state as evstate, detail.*, g.name AS _groupname , rr.rr_id, rr.freq,rr.rinterval ,MAX(rpt.endrepeat) as endrepeat ,MIN(rpt.startrepeat) as startrepeat FROM (jos_jevents_vevent as ev , jos_jevents_icsfile as icsf ) LEFT JOIN jos_jevents_vevdetail as detail ON ev.detail_id=detail.evdet_id LEFT JOIN jos_jevents_rrule as rr ON rr.eventid = ev.ev_id LEFT JOIN jos_jevents_repetition as rpt ON rpt.eventid = ev.ev_id LEFT JOIN jos_groups AS g ON g.id = ev.access WHERE icsf.ics_id = ev.icsid AND icsf.state=1 GROUP BY rpt.eventid LIMIT 0, 10

What does it mean?

And this appears above the table on Manage iCal Subscritions:

Manage Ical Subscriptions
Table 'joomla2.jos_jevents_icsfile' doesn't exist SQL=SELECT count(*) FROM jos_jevents_icsfile AS icsf WHERE catid = 34

I am having trouble getting this component to work. Could someone please decipher this code and offer a solution?

Thank you in advance for your help!
