I am trying to upload an audio mp3 file to my slides. I keep getting an "oops" message telling me that my file isn't accessible from your servers. The message says that this may be because I have entered the wrong URL or because my file hosting server is not responding.

Well... I am copying and pasting the URL and the site is a school site that everyone else in my class has been able to use to host their mp3 and upload them to slides share, so what is going on? I have been having this problem for a few weeks and I need to get this problem resolved asap for my deadlines. Thanks for the help.
