I click on a task (a successful backup of files/folders onto an external USB hard-drive) in the ATI ACTIVE TASKS window & up pops the following: 1. E006403FB The script is created by a newer version of ATI......cannot be processed....please upgrade..... this is followed by: 2. E00640066 The task script is corrupt......... After these messages, I can actually proceed to create a differential backup without any further problems. I have little faith in the backups I am creating. Please explain what is going on. THE BACKUPS WERE ALL CREATED WITH THE SAME VERSION & BUILD OF ATI HOME (3677). FURTHERMORE, THE BACKUPS WERE VALIDATED SUCCESSFULLY. Thus, these messages make no sense.
