Scheduled IP range scan is not working, at sheduled time

[vargaboti]

Hi, I think that I have a problem, and asking for advice. Since I have upgrade to ver.4 (23.04.2010) it seems that Scheduled IP range scan is not working, at scheduled time. Running manual IP range scan is working well. What can be the problem, or where to look for?

Nothing related to IP scan after 14:00 when the job should be executed in Errorlog.txt.
AD related scanning is working .

Are there any errors in your errorlog.txt file?
