Sadly, still no luck getting this to work. Core of the problem seems to be EPL not showing up on any of my toolbars. Also when clicking the pad no option to show GUI. Got to the point where I had a Mag-lev steady drilling/reprocessing/rocketpart producing factory on Minmus and xfered the rocketparts to the pad *which was then full of parts*. But alas, when right clicking no option to actually build. The base has since been returned to kerbin leaving behind a cargo container drone and the launchpad, sitting lonely in the highlands full of rocketparts.
