Can't add songs to a playlist in MusicIP Mixer

[Peru]

A while back I downloaded MusicIP Mixer after reading this thread by Shrimpy (Where is he? - Haven't seen him post in a while):

viewtopic.php?f=23&t=6109&p=55182&hilit=musicip+mixer#p55182

I noticed today that I can't add songs to an existing playlist or a new playlist. It just hangs, and uses 50% cpu until I stop it using Task Manager (running Windows XP MCE SP3).

I tried .mp3s and .wavs, both of which I've used in the past.
I can, however, play songs in existing playlists.

I tried uninstalling (using Revouninstaller) and reinstalling without any luck.
I recently installed Audacity on this machine, so I tried uninstalling that in case there was a conflict, but no luck.

I was going to purchase the full version, as I use this to preview my music (I don't mix, only preview) and like being able to quickly change songs with a single mouse click. I went to the website, but they are evidently no longer around.

1) Anybody have this problem and found a fix or have any suggestions?
2) Any recommendations for another program with playlists and a single button to advance to or go back to the next song?

Found this. Probably doesn't help.....

Thanks, John. I tried redownloading and reinstalling, but no luck.

But the good news is that I didn't realize that Windows Media Player can do all of what MusicIP Mixer can, except for mixing (which I didn't need).
