Fedora 15 Live USB does not boot
 

I have created a fedora 15 live image that does not boot.
After waiting a few seconds, I press ESC during the boot and I see several lines similar to the one below scrolling down the screen;

/sys/devices/pci0000:00/0000:00:1d......../block/sr1(35374).

I'm using LiveUSB Creator 3.11.1 to create the LiveUSB

Can anyone assist me?
