Hi all First, I have no idea this is the correct forum for this question, if not do apologize. After installing the Aerosoft addon for Madrid-Barajas airport, I flew from EBBR to LEMD. Radar contact vectored me to land at runway 36. But as I wanted to press the APP button to capture the glideslope (PMDG 747), I got an FMC message which said 'invalid nav'. After checking I saw there was nothing in the nav radio (keep in mind I already selected the appropriate runway in the dep/arr page). I opened 'map' via the FS-menus, looked it up and the frequency said 0.00. So there must be some error. I rebuilded the scenery databases after installing. Ps, I have no idea this error also occured before installing the addon.

There are two 36 rwys in LEMD: 36R and 36L.None of them is a landing runway, they are only used for takeoffs when the airport is in north configuration, so, no ILS there. You see:LEMD in north config. 36R and 36L for departures - 33R and 33L for arrivals.LEMD in south config. 15R and 15L for departures - 18R and 18L for arrivals.
