program does not create backups

Hi. I have a problem. The program does not create a copy of the image. He created the first image, but then does not update it according to the schedule. Bar appears with the inscription - queued. This can continue for several days, the image has not updated ... when I try to restart the computer appears on the screen such an inscription - "operations are in progress, please wait. The machine will be turned of automatically after the operations are completed". What do I do? Thanks for your attention.
