sfplay~ and preload

PSG's icon

I'm trying to learn how to use a preload message with sfplay~, then trigger that file to play with its cue number, but I can't get it to work. The sound file I'm trying to preload is in the same folder the Max patch is in. As far as I know, that should allow Max to find it. What am I doing wrong?! I tried both with and without the .wav file extension and neither way works. I also tried adding a starting point after the filename, but that didn't help either.

If I understand how this works, I should first send the "preload 2 singing" message, then send the "2" message, right? But it's not working.

... quick update. There must have been something haywire in my Mac last night. I opened up the same simple patch today and it works. I'm not sure if this function of sfplay~ is unstable or if it was just a fluke that it didn't work for me.
