Backup problem & Licence Key will NOT update!!

[AlexB@]

Plesk ist set to backup some 40 domain between Midnight an 6a.m.

Instead of doing it just once, Plesk wil do the backup of each domain up to 10x. This happened first, when we changed to daylightsaving time here on sunday morning.

There is only one cronjob set matching 'backup', s far as I can see in the Plesk-Cronjog Manager.

Any hints?

and, MAJOR Problem:

Licence Key renewal is failing. SCHLUND Support does not have a clue. I am within grace period till thursday. Logfile from /usr/local/psa/admin/logs/httpd_error_log:
