BDisk.sys IS NOT WORKING PROPERLY

I login with the adminstrator’s privileges, create a disk, partition, MBR backup to backup a single physical disk (SSD Crucial M4 256Gb) from my laptop. Comodo immediately shows a yellow panel with a message. The message says ‘Problems with COMODO Backup installation were detected. Do you want to see Diagnostic Report.txt ?’

The diagnostic report says “Diagnostics detected some errors (see uppercase errors)!”

The only error message I could find is

When I start the backup operation it fails to lock the system drive C: and crashes. A zero sized CBU file is created. The log file is not created. I am unable to copy the error message but I managed to make a screenshot before it crashed.

What is this bdisk.sys? I reinstalled the application, restarted the system, but it still says that bdisk is not working properly.

Please see my answer here.
Bdisk.sys is a disk driver used by CB for disk/partition backups.

Thanks
