Help is required!

The procedure entry point _DXPlayMedia@12 could not be located in the dynamic link library NDSound.dll

Can anyone help me? What does this mean? How can i fix it?
I really want to Use sv1.17 on *M* server/autobypass[4354]
Thanks. ^_^

r u sure u got proper conquer.exe for a proper version??
try reinstalling all game and download whole new client 4354.

Thanks for your comment, i did what u said, i re-installed but still same error :(

hmm i remember i had the same problem with ndsound in the past, solved in with some obvious metod ,don remember doe how... hmm try everythin what come into uer mind and run - blacknull command on original conquer.exe and see if it helps, if it does u better check one more time if u got 4354 version of multiclient.
also did u remove ur conquer totally thru add/remove programs?
