perhaps it's a hint,
that you'd be better off at the beach, than screwing with this!!!! 
You may want to try, naming your "working folder, as opposed to using the default folder.
I was getting, DIFFERENT AUDIO, after doing an operation!!!!!!!!!!!
I deleted and reinstalled it, but only when I renamed the working folder
did it finally work right.
under;
file
wavepad options;
audio processing;
audio working folder;
clik that button, then name your own folder and partition, like D:WavePad-working
that's what I had to do
