Just another addition.
I'ver tried again but the same result.

The file hts-log.txt shows among some other messages the following, that
descibes the problem maybe.
'Error: 	link not taken because of error (-4 'No data (connection closed)') at
xxx%40xxx.xxxxx.xxx:xxx@www.example.com/companydetails.php?orgID=7052&l1_catid=3&l2_catid=3&l3_catid=27&l4_catid=32&PHPSESSID=4740de5f33d105301315f4434fae1358
'

As the result of the pages, I see always a site to decide to invoice or
subscribe instead of the company details.

Does anybody has an idea fro me?
PS: Of course, I've replaced the true information by the 'x' for this posting.
