you probably did something that is hardly noticeable but makes enough trouble not to move... I did that a thousand times and I always say "Never ever" but of course I don't learn either... anyway, the best thing to do is sleep on it and think while you sleep... next morning with a clear head, open it up and try.. and try... and try until it works. It will... I have no idea what could go wrong, I never touched that part yet. just don't be mad and angry it doesn't help I always make mistakes when I'm angry. Also ask your girlfriend/wife what is she thinks is broken ? Many many times my wife helped me out with a perfect answer ! Womans has better sense and they think easier then mans. We always expect the worst and therefore not even looking at the easy small details. different brain works due to hormones... i guess... but then what about the homosexual's are they think like man or woman ?
