Well, I purchased and downloaded Liftoff (mandatory to create an account and sign up to STEAM, which is a Gaming software Company distributor) I could not find where to just download the software. 
I got everything downloaded, installed etc. The Liftoff opens fine but does not see my controller. On my laptop my DJI controller shows un devices as "C5", but says "Driver is unavailable" even though I can see it through the DJI Fly app.
Anyone know if there is a specific place to download a driver for the FPV controller? Any other suggestions?
Thank you
