After installing new add-on airports, I tried to rebuild the PF3 database, which failed.
I checked PF3 for updates.
I ran makerwys.exe that I used the last time (4.696), completed OK.
I tried with and without keeping the SID/STAR data. Both failed.
I used the link from PF3 to find the latest version of makerwys.
I ran that one (4.6991) with the same outcome.
I checked the Schiratti/Dowson page and found under FS2004 heading version 4.692 which is older than the ones I used, so I did not give that one a try.
Attached the runways,csv zipped.

P.S.
The only thing else I did after installing the airports was via Options 2 / Designated parking control for ENGM parkings 2, 3, 7, 10, 12 and 14. At least, that is what I wanted. After checking I saw I can reserve only one parking spot, which I did.
