I've tried to download the application, but there is no possible way since all the download links are dead or don't exist. There is also no official website to acquire the software from. If you receive the "File type not supported" message, then it means the software doesn't actually supports that file, even it says you can load WAV files. WAV files can use different codecs as well, and if the one you're using has a codec of that type, then it won't work.
