Notifications does not working

I try to setup some workflow notification but does not working at all. Neither transition notification or state notification. I must mention that send e-mail action from transition are working. We use database for communication. I verified also DocumentActionInfo and BroadcastEvent tables for any row. I restarted database service. Any of this solution does not resolve our problem.

If any body know any solution of that, please help.
