i had the same problem.... you need the old file of something-or-other because the new one isnt fixed. go to the winamp forums and search for what it says about the problem. mine is fixed, and i listen to music almost every day.
Not to mention, its so much faster. Media player is like a freakin resource hog. Winamp is like one click bam, windows media player is like one click, wait 10 seconds....Just my opinion
I think Winamps a great program. So many plugins available for it (Even if on the latest version, they are more unstable), but I prefer Media Player for music personally.
Weird problem though. Maybe someone should report it? And/Or download an earlier version?
Maybe www.download.com will allow you to download earlier sources.
