Could not access backup in Acronis True Media Home 2012

I’m trying to access the backup I created in Acronis True Image Home 2012. I saved it on a removable media disk. But I am receiving the error below when trying to launch it. How can I be able to cope with it?

Acronis Time Explorer
Cannot find the file or folder. If it is located on a removable
media or a remote storage, then make sure that the storage
device is connected, and try again. E:2My_Documents57.tib.
