Hello everybodyYesterday, I had fun with the PMDG 747-400 until surroundings of afternoon. I made the flight between San Francisco and Los Angeles. Then, I had the unhappiness to update the AIRACS data. Now, I have an enormous problem with PMDG 747-400 and 747-400F. It is impossible to me to choose a 747-400 or 747-400F. But well the PMDG 737-600, -700, -800 and -900 she function very well (In the FMC, the data are well up to date).That that this pass when me chosen a 747???simple: I Start FS2004. I select the PMDG 747-400 or 747-400F and when I click on "OK" button I have an CTD with the following error message:"The description for Event ID ( 1000 ) in Source ( Microsoft Flight Simulator 9.0 ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: fs9.exe; 9.1.0.40901; unknown; 0.0.0.0; 00000000."Then, what I would like to know: 1

Hello,For those that are interested. I succeeded by solving the problem itself. To begin, I executed the last update of PMDG 747-400.To this moment, when I chosen a 747-400 at the starting of FS2004, the plane was loaded normaly in memory (airacs progress bar). Then I let the airport by default and I start the simulation. The progress bar move until 100%. The cockpit it is displayed a fraction of second and then: CTD (same mistake). Next, I executed the last update of PMDG-747-400F then. By miracle, all come back to normal.At this moment, I try once to update AIRACS. Finnaly, Airacs is updated.What happens .... I don't known !Andre
