there was, indeed, but again no luck
It was D:\Program Files\mirc\sounds and then I moved the whole mirc folder to the root of D:\ and adjusted the paths in mirc so the sound folder is D:\mirc\sounds but I still get the error * Sound request: cannot find 'hello.wav'
I'm really lost...the file hello.mp3 is really in the sounds folder, the paths are correct and there are no spaces whatsoever...
