Hangup at starting Acronis Loader

I am running Acronis True Image Home 2010 on a brand new Toshiba All-in-One computer with Windows 7 64 bit. I ran the "Try and Decide" program and then hit the "Keep Changes" button. My computer rebooted and I now get this message: "Starting Acronis Loader...", then "Starting committing..." and then "Status of commit: 100%" There is a little figure that keeps moving left to right but the computer does not boot up. I've tried hitting F8 to get into Windows for "last known good configuuration" but this keeps coming up. I tried booting the computer up with the Acronis disk but couldn't see any solutions. Can someone tell me what I can do?
