GRRRRR VOICETHREAD!

Here I have been for the past 2 days trying to get get my lessons but alas, Voice Thread never wants to respond. I am the only one to whom this happens? I would really like to know why it is that this seems to be the only site that does not co-operate. >.< So if by any chance this has happened to you I would love to know why it's happening to moi and how I can get around it. Thanks!
