FS9 installation error messages

I have a XP machine and have instaled fs9 onto it, directx9 was detected as not present on loadng it in so it auto installed this first. The complete 4 cd installatuion goes in no problem, requsts a restart after install. Once this is done when you try to start up the game i get the following error messages.............
"some aircraft and software could not be loaded please click to continue without them"
then it runs a lst of errors
acontain.dll
a1-player.dll
atc.dll
controls.dll
dem.dll
facilities.dll
fe.dll
flight.dll
fsui.dll
gzd.dll
g3d.dll
instructor.dll
mains.dll
multiplayer.dll
sound.dll
symmap.dll
terrain.dll
traffic.dll
when i look in the modules folder within the game, al these files are present and installed.
Ive installed this version on other machines and suffrerd nothing like this before.
Thanks
Ivan
