Error: File is already loaded

[HisDad]

My scheduled backup does not run at all. Log says "Error: File is already loaded." What does that mean?
FBackup 4.8.286 on Windows 8

Full backup is scheduled for 9:00am every day.

Hi,
Please make sure you don't have multiple schedulers for the same job configured to start at the same time and you should also make sure the application is not open with that job selected.

Thanks for your help.
There is only one schedule for this job: Full backup is scheduled for 9:00am every day. No other backup jobs or schedules exist.
The application is not open at the time the job is scheduled to run.
The computer - a Windows 8 laptop - is in a state of sleep (or maybe hibernation) at the time the job is scheduled to run. The laptop's lid is down. Can FBackup 'wake' the computer to execute a scheduled job under these conditions?

Never mind - FBackup is uninstalled.

Hi,
Yes, under scheduled task properties, there is an option "Wake the computer to perform the task".
