I downloaded the K-Lite codec pack but it came with all sorts of garbage add-ons that I declined until it got to the end of the download and the final garbage add on was one that if you said no to it, that was the end of the ability to get the package. I also tried Audacity, but it couldn't convert the file and neither could FreAc.

I don't understand why they work for others, but not for me. I'm not a computer rookie, I've been into computers for more than 10 yrs. I've never encountered a problem like this. I guess the next file of preference will have to be either .wma or .wav.
