Error during encrypted backup of more directories

Hi,
I have tried to backup (in Toucan v.2.0) more directories into a zip (or 7z) archive format together with password. However the process failed when it started to backup the second directory in the list. Can you help me, please? Thank you.
Best regards,
Pavel
