age of empires II expansion help

[dhkim]

Hello All !
I just download ( again ) the patch for this one and put it on the right place. But when I launch the game it tells me that mmsystem296 couldn't be find or loaded but the game seems to run fine. Can anyone tell me what is this all about ?

I've downloaded this before but it never game to me that message.

Could anyone help me please ?

thanks in advance
