mail notification cannot change wav.files

I am running eM Version 7.1.30719.0 on Windows 7.

I have two accounts with a different wav. file for each one on mail notification and they have worked flawlessly until now. I have tried to change them yet eM still defaults back to the original ones. I have tried everything possible, but it just seems to have a mind of its own.

I figured it out. I was not scrolling down to access the second address. All is well.
