Hi I installed update 1.2 for the fs9 747-400 and have lost vhhx airport in the fmc,'not in database'.I use airac 0608.In blind panic I performed a system restore in xp but on starting the sim the 747 hung during loading of the airac and I got the 'fs9 has encountered a problem' etc message .So I then undid the system restoration previously performed and the aircraft loaded as normal but obviously still showing 'not in database' for vhhx.Does the update change something in the airac which could have caused this? ,or is there a simple solution I could try to get vhhx back into the fmc.any help gratefully receivedregards Jim

I have just read a few posts on this subject and tried a few things but without success .Also,I note that in the fmcwp folder the navdata files are showing 0802 not the 0608 that I used to have,so has this new navdata written out my previous vhhx ?.I am not too competent with airacs etc so apologies for sounding thick...regards JimEDIT: ok got it sorted ,phew....
