Hi I am having great problems with fs9. I have an external hard drive. I have backed uo scenery and aircraft (both add-on) and deleted fs9 and then reinstalled it. The scenery went across reasonably well, the aircraft all had missing gauges etc. I read somewhere that one can install fs9 on an external hard drive. exactly how does one do this. Also I get an error message on trying to load fs9 "failure to initialize Yak 40 Clos" and the program closes down. I ave removed all traces of this aircraft from the hard drive (internal) but to no avail. I realise that this is not a flight sim site, but I cannot even get acknowledgement of registration from the one site where someone had the same problem (& had not received a reply!) Bergman.
