I just loaded the program with the new patch. When I pull up the FMC, I get a "not in Data Base" message when I type in any airport. I Loaded the file from Airac, and created the folder in FS9 PMDG. I also tried to export a file from FSNAV using the export dll. When I typed the flight plan in the CO plan line, I get "system Error". I have the new version of fscuip, unregistered. Why is my pmdg737 not working?? Please help.Getting frustrated,Elton

The correct path for the the airac files: C:Program FilesMicrosoft GamesFlight Simulator 9FMCWPNAVDATA You must make the FMCWP/NAVDATA folders yourself. Be sure when you extract the airac that it does not make a dupicate folder within the NAVDATA folder. [h4]Best Wishes,Randy J. Smithhttp://img.villagephotos.com/p/2003-5/196432/winglets_lg.jpg

I will give it a try. Thanks for the tip, I'll let you know if it works.

Thanks, it worked like a charm. I would have responded sooner but I had to fly. Thanks again for the help. See ya in the skies.
