Module no working

Hi,
I have the latest version of this module installed and it just doesnt seem to do anything at all.
I created a newsletter issue and set it to "Send newsletter according to schedule" and in the schedule details I set it to Send Daily but upon submitting it just does nothing at all. If I then go back to edit the newsletter then under sending it just goes back to "Send one test newsletter to the test address"
I have tried it multiple times but always get the same result.
Can someone help please
