Unable to Pulse

The Pulse button is just greyed out and the pulse in the context menu does not do anything.

I was able to pulse when I first installed. It has been many computer restarts and I still can not pulse.

I’ve got 19 hours unpulsed time.

Windows 7 - WhatPulse 2.0
Just fiddled around and turned off work offline mode.

It works now. I guess I did not unerstand that setting.
