Further information - The large brown blob I mentioned was actually the back of a head of the pilot (me) and a co pilot has also appeared, which is possible as this is a most recent version. On re-loading the IXEG The following red script appears:
O.256: Load script: extensions/GateKeeper?GatekKeeper.lua.gfys: (string "extensions/GateKeeper/GateKeeper.lua.gfys"):599: attempt to index local 'json resp' (a number value)
This seems to be the problem due the de installed Gizmo.
