So I've just purchased LPPT and upon my first landing on the Runway on a Flight from Bristol, the Runway appeared not be a hard surface and my plane consequently 'sank' and all sorts of hills and things seemed to be out my front window. Thinking it may have been something I did wrong when installing it (not sure what - but I always question myself) I uninstalled, rebooted checked the scenery library in FSX which was clear of LPPT, closed FSX, waited 5 minutes, then reinstalled LPPT. Set my Airbus at Gate 122 and had a look outside and the pictures below show what I saw (even one of the buses are travelling 'in the air') and the little video shows what happens when i move around in FSX's 'spot plane' mode using my Joystick hat. Any ideas on why this is happening and how it can be fixed? Don't have the same issues with Aerosofts Munich, Dublin Zurich or Milan. I'm up to date on FSX, I use GSX Level 2 and Active Sky and those are pretty much the only addons I use during a flight apart from obviously the Airports. Everything seemed to be fine up until I installed LPPT. Any help greatfully appreciated.
