Dragon 31.1.0.0 Loses Extensions. Apps and Themes upon Startup

On 5th March, when dragon started (and auto-updated to 31.1.0.0) all of the pre-existing extensions, apps and themes are no longer installed - so had to be re-added.

Windows XP Pro SP3 (32-bit) on C Drive. Dragon installed on default path. User with Administrator privileges.

The same thing happened today (26th March), only dragon simply started (without updating). All of my pre-existing extensions, apps and themes have disappeared - and have had to be re-added.

Please do something about this problem, as it is getting rather tiresome.
