On your HDS, run this query:
select top 10 * from t_Agent_Event_Detail
Do you have any data?
From the HDS, maybe you can try this
select DateTime, ReasonCode from t_Agent_Event_Detail
where SkillTargetID = 5818 and Event = 3
and DateTime > '2008-11-20 00:01'
and DateTime < '2008-11-20 23:59'
with the appropriate SkillTargetID. Event = 3 is the not ready. Maybe a non-zero reason will appear.
