I had the same problem, I thinks its caused by the inibuild installer showing the instaltion complete, before its finished loading, if you come out to soon the terminal 5 is not fully loaded. I recently uninstalled EGLL and then re installed and left it running in the app until the HD drive light had stopped all its flashing. a good few minutes after the screen was showing as fully installed. Load the simulator and it was all working perfectly with Terminal 5 buildings all perfect
Give it a go and report back here, if you find this successful
