You should be able to click on the error report and get a specific error. Please send that in via feedback from your dashboard as that's something staff is going to have to take a look at it for you. I've not gotten one today but I'm using Netscape. Since you say bottom left of your browser, I believe you're using IE. Make sure that you mention that as well.
As to the audio, I'm on a locked down terminal which won't let me copy and paste. One thing to do though is make sure you're placing the code while using either the basic text editor or the code tab (not the visual tab) of the rich text editor if you use that one. if you look at the source code for that page, you may note that the URL is getting encoded. That's usually a sign that you're placing the code while on teh Visual tab.
edit: That audio code is right by the way. (If anyone else gets an error when they click on it, the trailing square bracket is included when it shouldn't be.) We've had folks previously try to link to pages that the audio appears on and I wanted to make sure that you weren't doing that,.
