Hikvision NVR DS-7116-SN/P - troubles with configuration

Hey guys,

I've bought an Hikvision NVR DS-7116NI-SN/P, with firmware V2.3.6 build 131120.
After many hours, I've succeeded to configure the EMail, and EMail test is going great and sending me emails.

I've tried to configure motion alarms by Emails, and to attach an HDD and failed with both of them.
In Motion detection tab - I've defined motion detection area and marked 'Notify Surveillance Center' and 'Send Email' but nothing, I'm dancing...
