Hi, and welcome to the forums
- Check that you've enabled the option "Play sounds while busy" (it's in the same screen as the MPG1 and MPG2 codecs.
- Also, in the Instant Messages section of the preferences, Commands & Tags subsection; make sure the box named "Use sound commands" is checked (I don't konw it's exact english name)
- If none of that works, can you answer me if you can hear MP3s in your computer? What version of Windows do you have? and what's the version of Windows Media Player? Try to reinstall WMP (or install the last version of it). Also, make sure you have the last version of Msg Plus! : 3.01.94
