Hi Simon,
When you signed up for the Backup Service, you should have been emailed full details about how to access your data. The URL to use is :-
http://pioneersoftware.backupaccount.com
Please follow the above link, then simply enter your USERNAME and PASSWORD (which were emailed to you previously) to log on to your backup account. From there you can access (and restore) your backup files.
If you need any further assistance, please contact our Helpdesk and we’ll be happy to assist.
