Yeah, I think it's pretty late where you are so not surprising. Maybe it's a good time to call it quits for the night and get some rest. As alluded to before, computers are very picky and everything has to be pretty close to perfect or they get messed up and take tons of time to fix the mistakes and undo the damage. So as you're going through, you'll want to be super-focused and work your way through slowly step-by-step, making sure you get every single one exactly right. Going faster to save time will cost you (and me) way more in the end. As they say "speed kills" and it totally applied in the computer world. Get some rest!
