Thx, for letting me know. :)

I installed the same version 6.2.0.154 on another computer, and it seems like the option is missing there as well.

Have this option been removed from version 6.2.0.154, or moved to another place?

Running CloudBerry Backup Ultimate Edition 6.2.0.154
Signature version 2

Yes, we got an email with link, until 2.weeks ago.
If i'm not wrong, I upgraded CBB to latest version around that time.

Forgot to mention that we have a S3-Compatible Cloud share, and know for sure that the report worked until 2.weeks ago.
