I am trying to land on Duna (had a similar uissue with Kerbin). I lowered my PE to 200m, but as soon as I got into the atmosphere, I started to rise. So I lowered my PE more. But I was still rising, Finally my PE was -300km and my speed had reduced to 14m/s. I was 46 km up and effectively stationary. Restartinbg didn't help.
