A re-installation did the trick, and adding SP1b. Any ways, thank you for your rapid troubleshooting & support, Vaughan!

Same thing happened to me, while reinstalling.

I checked in the PMDG folder, of FSX: 600/700: v1.00.3118, 800/900: v1.00.3118Reinstalling now. Do you know whether or not I need to install the SP1, or should I just install the SP1b?

Well, I honestly can't remember in details, but I can remember that I installed both of them, as I saw the title and the notes about this; "737-800/900" and "737-600/700".And yes, I know SP1 was before -this I followed, as well as the other installations.If I was to reinstall (which I probably am going to do, as noone really knows what went wrong), do I need to installer "SP1" again, or should I just installer the "SP1b", for both of the series?

I installed the SP1b for both of the add-ons after the RTM (737-600/700) and SP1 (737-800/900).My video card: ATI Radeon HD 5570Processor: Intel Core i7 CPU 870, 2,93 GHz, Quad-coreRAM: 8GB DDR3OS: Windows 7, 64-bit

Will modify my profile then :)Thank you VaughanI do not think it was corrupted, as I downloaded it from precisionmanuals.com (the SP1 updates).I think I had installed the "RTM" updates before that, as I experienced problems with the FMC, crashing FSX as I filled in the cruising level, before the 736/737 expansion came out.To answer your question; every single add-on (both default and pay-ware) works perfectly -except PMDGs 737 NGX 800/900 and 600/700 (with the problem shown above).(PMDGs 747-400 X and MD11 for FSX works perfectly).Last time it worked was... December 25th & 26th (long-haul). This was before I installed the updates -did not check up on the problem after I installed the updates, so these must have been the problem.Matias Larsen
