Recently created problems in SlideShare tagged with audio

I completed my slidecast last evening, without any problems. I then received word from my users today that the slidecast is playing back at a faster than normal speed. I now am unable to play my slidecast at all.

what is the issue?

For some reason the audio that we have uploaded is not being accepted in the syncing process to create a slidecast for our presentation “Start your spiritual journey”.

The URL for the audio is http://www.spiritualresearchfoundatio...

Can you please advise what could be the matter. All the parameters of the audio are the same as the previous audio uploads that we have done.

Slideshare has been working perfectly... until now. For some reason when I try to create a slidecast, the Synchronization Tool loads a blank box? I point it to the mp3 I want to link up with, it seems to load fine, then loads the Synchronization Tool, but nothing is in the box! Any suggestions?
(I get the same result in FireFox (WinXP and OSX), Safari, and IE.) Oh, the slideshare plays fine -- I'd just really like to use the Synchronization Tool.
