Hello experts

Being a totally new user of this software I failed already with my first try.
The files I want to download are from a password-protected site to which I
actually have access. The site seems to use javascript to open pdf-files which
I am then allowed to download. But this is tedious as it is many files I need
to download regularly. That's why I wanted to use httrack. Here is the error
log I received:

Thanks for any help! (And please, talk plain English, as I am not a computer
expert... ;-))
