Error 88780078

I have installed Winamp player in my system running windows xp. My problem is that whenever i run a sound file i get Error 88780078 and i am not able to play that file. I don't know whats wrong with Winamp player in my case. Windows media player works fine and i don't have any issue with it but i want to get Winamp player working as well.

I think you will have to download and install WGAPlugin and for that you can download WGAPluginInstall.exe file. You can check out Microsoft site for the same, in case you don't fine it there you can download it form some trust worthy third party site.
