Seasonpass problem

Everything has worked fine up until the tethered boot. The software completes and let's me know that it's ok to remove the usb and plug in the hdmi. But when I do, the image on my television is an itunes logo with a usb cord sticking into it, so basically, it's telling me to do the tethered boot which I just did? I'm not quite sure what to do from here. Maybe I should switch to a different jailbreak, but Greenpoison froze my mac pro to where I couldn't use my keyboard or mouse. Is anybody having the same issues?
