Full error message upon attempting to open the client: "The ordinal 11 could not be located in the dynamic link library DSOUND.dll"
I downloaded 0.4.000 using BitTorrent. There are six items in the PlaneShift folder - client, two guides, setup, updater, and uninstall.
I have no idea what an ordinal or a dynamic link library are, or where they should be, or what they're supposed to do, so yeah...
EDIT: Oh, and when I saw the word "sound" I tried disabling sound from the setup screen, but that didn't do anything either.
