Welcome to the forums!

Use a Bitorrent client like U-Torrent to re-download the iso.
If the new iso doesn't work, then try using something else other than Unetbootin (it failed 5 times for me today!) like LILI. ( www.linuxliveusb.com )

EUREKA! I solved by installing poweriso!!! unetbootin and linuxliveusb are not updated with ubuntu 13.04 and this causes problems with boot! thank you so much!
