Hi Bjørn,
You had this problem before, if I recall. Can you add this column with the following script which is sourced from the HF1 database scripts?
if exists (select 'x' from sysobjects,syscolumns where sysobjects.type='U' and sysobjects.id = syscolumns.id and
sysobjects.name ='dc_general_settings' and syscolumns.name = 'assisted_dispatch_hours_ahead')
ALTER TABLE dc_general_settings drop column assisted_dispatch_hours_ahead
GO
Otherwise, I think you should run the HF1 upgrade installer with the option dbupgrade.txt and point it to your new database you migrated. This is because your database from DK was not upgraded after connecting it. Anytime you are connecting a new database, it needs to have the same database scripts run against it for the 15 SP2 and also HF1.
