If your software was "completely up to date" then you should have support for the camera. What is the exact version of Lightroom installed on your computer? You need at least Lightroom 6.1.1.
This is LR CC (2015) VER
The version is only listed as LR CC. But when I when I went to update, it said all apps (LR CC. PS CC and Briodge) were up to date. So there is no version listed for the CC apps other than to demonstrate that they are up to date.
In Lightroom, click on Lightroom > About Lightroom
There will be a version number shown in the box: something like CC 2015.8.
What does yours say? Needs to be at least CC 2015.1.1.
