Getting error message when click on Events Menu Item

On industrynetwork.net.au when you click on Events menu item you get Nothing found message. This has only just happened was working fine previously (events still appear on a vertical slider).
Have tried with different themes but makes no difference.
Also in Wordpress dashboard when go to Events-Getting Started-Events Achive it brings up the Posts/Blog Archive instead of Events Archive ??
Support Access has been granted to you till 25 April
