The PIER Diploma course requires one of the latest browsers to function properly. You must use the latest version of Internet Explorer or Firefox and the security settings must be set as follows:

Internet Explorer requires most Medium-High security level. To set this level, go to Tools > Internet Options > Security and select the 'Default Level' button and slide the slider to 'Medium-High'.

Firefox requires Javascript to be enabled. To set this correctly, go to Tools > Options > Content and make sure the 'Enable Javascript" checkbox is ticked.
