Big Problem

I am using the latest version of TI, and I create a full image of my C drive in the secure zone (which is on a separate disk) so that if my Raid 0 stripe breaks I can recover it from acronis. I have successfully tested recovery on a previous occation however today I created a new backup after applying new video drivers, MS updates etc. Acronis informed me that the image was created successfully. but when I went to verify it it give me the following error
'Failed to open the image archive in the Acronis Secure zone'.

Now, when I try to explore any of my backup images (in the secure zone) I get the following error 'Acronis Secure Zone does not have any images'

What has heppened to my images? What is the point of the secure zone if it is going to corupt itself? I no longer feel I can trust this program as a secure backup.
