Hmmm ... 497 reads (498, if you count mine!) and no one even hints at having this problem or offers any solution.    :-?  

Well, I too have this problem (amongst several others) trying to run FS9 with Windows 7.  In my case, I can enter new repaints into ACE, it tells me it can see them, but they don't show up in FS9.

Some helpful reply before another 9-months pass by would be nice.   ::)
