In the latest version 4.2.2.15 backup fails with code 100144

When I try to start a full backup it gives me error code 100144. This apparently only happens when I exclude a folder somewhere in c:\users (like “Temporary Internet Files”). The full log is below.
All other options are standard. If I don’t exclude folders it works.
Makes me wonder… has this been tested at all? This is very standard functionality and it fails…

Hi!

This issue will be fixed in the future releases of COMODO BackUp.

Thank you for your support!

Never mind… I have uninstalled your product. If I can’t trust the backups, there is no way I can trust the restores. And that’s what this product is about.
Obviously the changes in the latest release haven’t been tested properly!

Still don’t work? I have the same error:
