Apple Configurator 1.2 - Taking forever to download iOS 6 software

So I just downloaded this update and I'm attempting to use it to sync up 22 iPads that I use in my classroom. Prior to getting this update, when iPads were plugged in, I was getting an error that said "Can't install app." Now that the update is installed, I've plugged in my iPads in an attempt to load apps, however, they now all say "Downloading iOS software." They have said this for the better part of the past hour and don't seem to be progressing at all. All of the iPads already had iOS 6 installed from the update released a few weeks ago. Should it be taking as long as it is with seemingly no progress?

Thanks
