Need Help Converting Audio File Formats in Easy CD Creator 4 and 5 Posted April 3, 2006 · Report reply Hello Steve, You may have upset the MP3 Fraunhofer codec that ECDC uses. It would probably be worth looking for a version of the Fraunhofer Radium MP3 codec on the Internet, and installing that. It should take care of your MP3s. If it won't recognize WMA files, you may need to do a repair of your Windows Media Player. Check and see if your current Windows Media Player will play them. If it won't, then it needs to be repaired. Just repair WMP, don't upgrade it. The later versions can and do kill Easy CD Creator 5.
