LGAV, PAI and AFCAD problem

[brynjames 0]

Sorry for the acronym soup.I am just enabling the standard PAI aircraft and flightplans, and added George Dorkofikis's LGAV airport so I could watch the Olympic aircraft. I then attempted to import and save Felix Hippmann's afcad file. This appeared to import and save correctly, but when I re-opened LGAV in afcad to check that all was well, the display was blank, and centred at about 0 degrees N, 0 degrees W, rather than the correct location.I then tried Panos Georgotas's afcad files: these seemed to load and save ok, and show up correctly when the airport is reloaded, but I notice I have now 2 listings for LGAV when I run afcad.A check on the traffic showed lots of aircraft taking off, but I didn't see one landing over an extended period, and Traffic Look didn't show me any approaching aircraft, so something isn't right yet.Any suggestions please?
