Defense+ issue

Hey there!
Using CIS an year already, i’ve recently upgraded it to v.4.
Imported configuration, found good theme, all seemed to be ok.
But… When it comes to allow/block dialog of defense+, and i press “allow” (“remember my answer” is checked), comodo seems to block application. When i am starting this application again, same dialog shows up. I am pressing “allow” - voila - “Error 5: access denied”, for example. Like if i have pressed “block”. In v.3 everything seemed to work this way, what am i doing wrong?
Sandbox disabled, def+ and firewall at “safe”.

What happens when you use not your old configuration but one of the v4 configurations?
