Well you're doing better than me - I've been stuck at the first hacking tutorial for he past one and a half hours (!) and I cannot for the life of me work out what I'm spposed to do! The numbers keep changing, and even if I do manage to find a sequence that stays still, it changes by the time I manage to drag the code sequence to where is is...or rather was. Can anyone help me out? Is there any way of proceeding without having to undergo this seemingly impossible task? I feel like Sysiphus here, and it's really wrecking my enjoyment of the game - what little of it I have been able to see that is.
