I've always had this problem with limewire for when I'm downloading a video file, I try to click the preview button when its at least at 15% to see if what I'm downloading is what I actually need. I'm sure we've all experienced when you spend ages downloading, and then playing, then realising its something you don't even want. When reading the forums, Ive done the bitzi searches, but it says unknown all the time.
I'm not really sure why I can't preview my files. Can anyone help me out?
