Active Wall Expired on free version

[luminiscence]

Installed free (as I understand from description) Active Wall Web filter one month ago
Created time range and set up url and mime filters on it - all works correctly.
After what tool was not used some time (service was stopped and set start mode to "manual"); today I started it and found that:
- filtering is not longer working
- application title is "Active Wall Expired" - for free version - ??
- allowed to import/export policies, but policy config could not be opened (menu Group->Policy config is empty and clicking on it has no reaction - nothing happens)
So question is - am I need some kind of "free registration" or software is not working by another reason?
