Why don't all the sound files I upload work?

Question

If I upload 10 WMA sound files, which all work perfectly on my computer, 2 or 3 will upload and not play. Instead of a scroll bar I get the number "404"

Answer 1

make sure the file isn't over 5mb and check at the bottom of the files section to see how much space is available. it could also have to do with your server and timing out
