That's better

but still not top,
don't bother , we will walk across
this one also.
now there is two possibilities:
1- bad install/directories of OrbiterSound
2- exotic folder path name
SOLUTION
-------------a) check that into your folder Orbiter you have a folder
Soundyour Orbiter directories must contain folder as follow:
Sound
Sound/cfg
Sound/Docking_Sound
Sound/radio
Sound/Vessel <--- this one must contain lot of wav file
Sound/Vessel sound SDKif not unzip again the OrbiterSound archive
into Orbiter's folder and
don't forget to check "Use folder Name" in winzipWinzip install window must look as follow:

b) check that your Orbiter's folder isn't into an exotic path:
ex: Program Files/~MyinstallGame/Orbiter
blank space or exotic character (^ ? , etc etc) as well as specific language character (accent, special letter) in the path will not be liked by OrbiterSound (and also some add-on)
the best path would be something like:
C:/Game/Orbiter
or
C:/Orbiter
As Orbiter don't write any info in the registry you can move your Orbiter's folder as you want at any place in your HDD.
Try this and tell me if it still not work
