[Moved from Winamp Tech Support to Discussion]
Hmmm.... so what do you want us to do about it exactly? This cd+g plugin you refer to is made by a 3rd-party plugin author, and 3rd-party plugins aren't supported here. If you've got any problems with 3rd-party plugins then you need to contact the plugin author, whether to complain or ask for help or whatever... and explain to him/her in as much detail as possible exactly what you mean by "it doesn't work".
Which plugin is it anyway? One of these maybe?
