I tried that-the only link I can find is for filefront(I think it's called). When i go there they have a couple mss32.dll files but it doesn't indicate what version they are and they're all different sizes. If you can google and find it please link it-thanks!
A large number of games out there have a Mss32.dll file you can use (it is just the Miles Sound System), so you might want to check any other games you might have installed to see if they have the right version. A quick search of my own system turned up 21 copies of the file in Darkstar One, Neverwinter Nights, Call of Duty 2, The Witcher, Sacred Gold, Painkiller, Shogo M.A.D., Half-Life 2 (and all other Source based games), Battlefield Heroes and of course, the KotOR games. Not all of them have version 22.214.171.124, but quite a few of them did.
If that doesn't work for you, I believe the file from FileFront that is around 365K is the one you want.
