Hi All:I had a complete computer crash and after doing a complete re-install of everything(fs9) the B747-400 does not follow the magenta line during a flight. The plane seems to be pointed at a 45 degree angle to the magenta line. I am wonder if has something to do with the navdata. I had never updated to the 2.1 or whatever the last update number was until now and I believe that is the version I downloaded to re-install.Any help would be appreciated.RegardsRickAvsim Deputy Library DirectorAvsim Online!

Run the FSX/FS9 Registry Repair Utility.http://www.flight1.com/view.asp?page=library- Bill

HiThis repair tool that I have seen mentioned numerous times, should you run it as a precaution or only when you have a problem?RegardsStuart

Certainly, it cannot hurt to run it as a precaution.- Bill

Thanks for the reply.I do have that registry repair program and will run it again.RegardsRick
