Hi Bianca,
Thanks for getting in touch!
We’d be happy to help — but first, would you be willing to open a thread on our WordPress.org forum? We use this Pre-Sales channel to answer questions about purchasing our premium plugins but do a weekly support pass for the free plugin over there.
In the meantime, please note that the Month View will only allow you to navigate in the future until there are no upcoming events. So, in other words, if there are no events after December 2016, then the navigation will be hidden.
Cheers!
Geoff
