Can't get Baku 17 or 18 track into my AC content manager

[thebackgroundman]

2016 is in there ok and works fine but the Azerbaijan GP 2017 v1.1 update folder files simply won't work. Is it something to do with the file type which is a .MAS? I have never seen these before...
When I unzip Azerbaijan GP 2017 v1.1 there is Baku_2017 and Baku_2018 inside plus those .MAS files. How do I get these to work in AC? Extracting the Bakus into my tracks folder as normal doesn't work. I've tried putting the .MAS files inside the Baku 18 folder and still nothing.
Any help appreciated!

I think you downloaded tracks not meant for AC ... AC doens't use MAS files.
So that's why it cannot work in AC where .kn5 files are used.

I got these files from a search for AC Baku tracks... ok I will check the compatibility of any other mod I locate. Thank you for your insight.
