You can download your data at any time by logging into the web based app and clicking on 'download my data' in the bottom left hand corner of the home page.
Please note that in order to get a session to download it must exist in the system, so for any sessions for which you have not emailed or printed a report you will first need to create them before onloading. The easiest way to do this is to use the task center on the home page of the web based app, you can click on 'session reports to print/email', select the reports that have not been created and click print. The system will then create all of the reports to you before popping up a print dialog box which you can simply dismiss without actually printing anything if you prefer.
