[Solved] How does this addon work?

Hello.

I've purchased without any doubts and installed on live site, but this is working in an unexpected way.

I thought this message addon would work the way most chatting apps work, like skype and gooogle hangouts.

But when I click on Send button, it refreshes the page and the message is not listed on the receiver's side either until receiver reloads the page.

Is this how it is supposed to work?

Thank you.

Noy.
