Sorry, I could not find a topic on this but I have a ticklish feeling in my brain that this may have been mentioned.After a long time I installed the 600/700 + 800/900 models on my machine. They work just fine, but some other addons like the Level-D 767 and the PMDG MD-11 fail to load. Any attempt to load those aircraft, either via a saved flight of a creating a new flight ends by FS9 crashing due to unknown module when the scenery load bar 0% appears.Any ideas?

Never mind. Found it. Some aircraft (PMDG 737 is one) install an old version of the gaugesound.dll file which is not compatible with Fs2Crew (which I have installed for both affected planes).It can be restored with FS2Crew's start center utility.Staff, you may want to mention this in the FAQs and readme files.
