After I installed the 800/900 package, everytime I start FS9 I get a message that says there is "incompatible software." The file name it mentions is dlB737FPL.dll. I am able to click "yes" to run the software, and everything seems to work fine.I am just wondering if this is a known issue, or maybe someone knows how to fix the problem? My search of the forum came up empty.By the way, PMDG, excellent work.Brad Brooks

Maybe you should add:[OldModules]FSSound.dll=1dlB737FPL.dll=1to the FS9.CFGRegards Leopoldo
