ok so i am trying to jailbreak the ipad with 4.2.1 using redsn0w 0.9.2.b4 and whenever it gets to "Waiting for ipad to restart i get a picture of a hard-drive and then windows gives me a message that says it has stopped responding.

i get the option to "Check the internet for solution" or "close program"

so i close the program. i tried re-downloading redsn0w and same issue.

so i tried re-downloading iOS 4.2.1 for ipad and relaunching... no dice.

Then i tried running redsn0w in compatibility mode (XP SP2) and same issue

Any help?
