Does it show any seeds or peers?
Check the "tracker" tab and the "peers" tab at the bottom of the screen. You just may be trying to download something that has no seeders at the moment (see if it appears in the "seeders wanted" box on the home page here).
As it seems to be the same for all the torrents you are trying, it's possibly how you have set up uTorrent but do check that there are seeds and also that the torrent is still here and hasn't been removed.
If you downloaded the torrent files a while ago, try re-downloading them and trying again - just in case something went wrong with them.
Do let us know which files you have tried - it could help.
Don't worry, we'll get you up and running. It will probably be something very simple that needs doing.
We've all been there
