Problem with Soundtaxi: distorted audio when converting Audible .aa files to mp3

[any ANONYMOUS forum user]

Why has my audio recently become distorted when I convert aa files from Audible to mp3 using Soundtaxi?

I have been downloading an 11 to 3 satellite radio show from audible. I have been converting the files to mp3 using soundtaxi. I am using the old version of the audible media filter plugin for windows media player method to do this. This had been working great and I could listen to the show wherever I wanted. Lately though (within the past month) the files have been distorted and there are skips and major distortion every so often. I did not change any settings in sound taxi or make any major changes to my computer. I am very conservative. It is mostly a media server and to do things like this.

When I listen to the files using the audible media player the files play absolutely fine. I am thinking this might be some kind of new DRM or something. Has anybody else had this problem and/or know how to fix it?
