Password reset not working - not receiving reset email

Seems like a simple Wordpress function, but the Password Reset is not working for me on my site.

Steps to replicate:
1. go to home page to login: xlearn.net.au
2. click on the "Lost my Password" link
3. enter in my email user email address
4. click "Get new Password"
5. wait for reset email to arrive...

...and it never arrives.

Some questions:
-is this a Cron job issue, that is related to my Host (GoDaddy)?
-if so, is there a plugin to resolve this issue?

Thanks guys!
Cheers, Brett
