After Absinthe got to the point where it says "Sending initial jailbreak data" it stopped doing anything and the window went dull like programs do in Windows when they stop working. It's been like this for several hours. My iPad is completely usable right now, though it did go to the update screen for a few seconds before going back to the lock screen. I decided not to erase all data "though I did a backup" because restoring would take a long time and they said it's okay to not erase all data but it will make the jailbreak take longer. Should I force quit Absinthe and try again, or erase all data before trying again, or is it dangerous to quit it now? Thanks.
