Sound Effects Using Instabuttons

[WaltR]

I downloaded some of the sound effects posted in the "sticky" for use with the instabuttons. The "crank it up" file works fine. All of the others work in Windows Media but when I use them in Hoster as an instabutton they don't work. When I look at the file in Windows Explorer it shows a time duration of 22 seconds for example. When I add this same file through Hoster as an instabutton, it shows a duration of 0. This is why it won't play but I can't figure out why this is happening. Any ideas?
