In ActivInspire both Personal and the Professional you can edit the clock settings. To do this, please go to File, Settings, Clock Tool. It gives a few options regarding the analogue and the digital settings.
Please ensure that you remove the 24 hour tick from the box, and select AM/PM.
I hope this information helps.
