OMWings C-140 problem: wav file?

Been looking for a decent Cessna 140 for FS9, and the two freeware ones I've found are not quite to my liking.
Took a chance with $7 on the OMWings version, and once I undid the stupid auto-installer's folder creations, everything seemed in order, and the model shows up in FS9... until I click "OK" to select it.
Then, FS9 hangs, and after I use Task Mgr to close it, I see the following message:
DirectSound: c140_click 1.wav failed".
I went over the sound folder and the sound cfg with a fine-toothed comb, tried deleting that wav, tried everything, really... but no joy.
I'm pretty sure this particular click is supposed to be heard as you select the aircraft; I've seen this annoying little feature with other payware birds.
anybody have any ideas?
