mp3 player suddenly quit working properly

I created a website using flash mx 2004 approximately 6 years ago, and it has been up and running without any problems until just recently. I didn’t make any changes to the movie itself, just published a new swf, html, xml and added some new mp3 files to the directory. We’ve contacted support from where the site is hosted at and was told that they were having some issues with some of the sites running slow or timing out, and that I should republish and re-upload my files. Did that and it did not help. Could it be an issue because I am still using such an old version of flash?

website is at okiboki.com

Thanks, in advance for a little help!
