iTunes freezing, 1600 error if I manually restore

probably the 10th time now, but every time seas0npass opens iTunes, iTunes crashes/freezes.  once iTunes recovers, I try manually restoring my ATV with the ipsw that seas0npass created and it fails with a 1600 error.  any ideas?  is there away to completely remove seas0npass and all of its settings and try again?  don't remember what option I chose on first run.
