Problem solved!! So after some more mining of the posts I found where someone had an issue with not being able to click on buttons in the UI. The fix for that and for me was to go back to the desktop icon and in the compatibility tab, re-select the option of allowing full screen optimizations by clearing the check box. This did the trick and now the UI functions properly with respect to being able to click on any and all buttons! So the initial crash problems going into setup was fixed with the steps in my post above by adding the line to the Falcon BMS.cfg file. Then making sure to allow full screen optimizations. I also deleted the dx9display.dsp file in the users/config folder after each display setting change and before reloading BMS. I tried many resolutions higher then a 1920x1080 since my display is 4K UHD capable but certain in game screen text did not display correctly so I think the best settings are to stick with the 1920x1080 and just change the display card output to full display panel versus keeping 16:9 aspect ratio. It stretches the image a bit but its worth viewing the world on the full 65" display! Hope this helps someone!
