Definitely watch out to have all your connectors above the board. I managed to get my #5 connector trapped under it. Still hope wasn't damaged, we'll see in a few minutes :)
Actually, I had to apply some pressure to #7 to get it back in place - I tried not to force it as advice above said, but it wouldn't go in. The pressure wasn't too strong, but it doesn't just slide right in.
Same - the key is to start prying with a screwdriver, not a plastic spudger, but make sure to keep away from any wires.
