Sorry on that last post, it shut on me so was not completed. Here we go again:
OK, didnt get a reply here, so I unactivated the KIAH scenery, deleted it from my P3DV4.5 scenery, and then deleted it from my computer. I then downloaded the current version of KIAH (2.1), and reinstalled on my computer. I then reactivated it by putting in my serial number. It said it was activated on my computer. The floating planes are gone, but now there are other problems. During installation, and the ensuing FSDT updater running, it said the AFCAD was updated, and did I want to overwrite the old one. I said Yes. When all finished, I started up P3D, and went to KIAH. I then opened the addon manager, and clicked on KIAH. It said it was in trial version. I clicked on the register serial number button, and entered my serial number. It said my scenery was now activated. It does not appear to be all there though. The runways, and taxiways do not look right, and the only buildings showing are the UAL maintenance hangars. The terminals are all missing, and there are huge holes in the ground. I see the trams running up in the air, but no buildings. Something is seriously wrong here. I never had any problems until the latest update. Help! Oh, and I DONT have any other KIAH scenery or AFCADS installed in P3D.
