FS9 and D3D9.DLL error

[wan2fly99]

When I start FS9 I get this error D3D9.DLL error

I usually re-boot the computer and then FS9 starts most of the time

Would anybody know what this error would be?

Thanks for any help

D3D9 implies it's part of Direct X. You can run dxdiag and see what
it says or try install DX9 again.
