After "updating" I now only have two planes. I tried the advice about uninstalling trying to make sure I deleted everything but this did not work. I contacted the Microsoft help website and I have done what they advised which was to make sure the APP was downloading to the correct place (Drive D) which it was. The next thing was to go to PROFILE >CONTENT and to download the content I required but this screen only showed me the two planes which were already downloaded. I cannot get any further with Microsoft so I am back to the real experts. (grovel, grovel)
