When I originally started the download of the new build, I ticked the option [Start once downloaded]

I did this and nothing in OPTIONS showed the shoulder buttons that would allow K E R's to work.

After a further shutdown and restart of the gaming PC, when going into options, the shoulder buttons now appear in Options, but, sadly, the trigger mechanism to get KER's operative, still isn't working .... well not working as I suspect was the design.

Got me stumped ???
