I'm trying to get BrawlEx to work however I crash whenever I get into the title screen. I am using Riivo on a PAL Wii and PAL SSBB. Can anyone help?

I'm trying to replace DKs announcer call with one for Shadow however when I do all the necessary steps and press insert I get this in the console
Inserting wav Shadow Announcer Call-old1.wav

sndconv.exe v1.2
Sound converter for Dolphin AX sound player.

And nothing changes. Can anyone Help?  (i'm using PAL if that makes a difference)
