SoundCloud Widget HELP!

I embedded Soundcloud code into my WordPress Posts a month or so ago and the player worked fine. Now, when I embed the same code, and even if I go and update a blog with the same original code, the player and the code actually disappear when I update…what the heck is that? Anyone know how to fix that? I want the player to play on my blog, not a link to soundcloud where you leave my blog site.
