Ok I know its an old game.....

I tired to play it on my PC and during installation it does a sound test which does just fine, BUT when I play the game itself I have no sound any idea why ?

On Yoda's Help Desk (at the LEC site) it tells how to install it to your hd a certain way, involving command lines. I am too tired to look it up just now, but I had similar problems (the music worked, but the sound effects wouldn't play) but it works fine now (well, I had to reformat, but it worked fine then).

I found if you have the Win95/98 version, the launcher only works if you install the game into "C:\DARK\" too btw.

Check the site and see if their instructions help....
