Events calendar plugin wont install properly

I have tried to install the plugin on several ocassions the same way I have done for other plugins. It becomes activated but the only sign of it working is a calendar icon that seems to go back to my homepage. There is nothing I can see in dashboard or any way of using the function on the site whether logged in or not.

HELP!!
