First, reboot the device, then restore the backup and see if that fixes it. If not, use a file browser such as File Manager + and see if the file exists at the location specified by MobileSheetsPro and that the size is greater than 0 bytes. If the file does exist, then we can look into other things. If it does not, well that's a problem as the backup doesn't have the file in it, so you'll have to use the file swap feature to swap in a valid version of that file.
