Only two? Lucky you. I've done that more times than I would like to admit. But ripping out solves the problem, and going back "slowly and surely" will fix it for you; for me anyhow. Speed is not one of my long suits, and when I hurry I make boo boos. I have also found that if I check the signs before I start something, I have better luck ("signs" being the zodiac or almanac signs for you who are not of these Southern leanings; and I say Southern because I am of Southern upbringings and don't know any Northern folks who admit to this kind of thinking).
