Hi Ian,
The database holds 210022 aircraft records as you state and thats what my d/b has after downloading this morning. EC-ICS isnt in the Navdata or on the server having been removed in November. For some reason you have an extre 1300 records and I have not got a clue why but some other users appear to have this as well, may well be that for some reasons some records are not being deleted if EC-ICS is in your Navdata. It will probably date back to the first beta upgrade. When you download the Navdata update do you go for Update all Records (overwrite the local databse with the server databse)? If not try doing that.
I cannot manage to come over this side of the New Year as there is a steak and sausage pie waiting on me here with my name on it. :-))
