Yeah, getting the board back into the "rails" was a royal pain. Had to pull it out and put it back several times. Does gentle pushing once the board's lined up do the trick or is a bit of force necessary? I'm really shy when it comes to being firm, especially with things I care about. And the button on the back didn't do anything either.

It's possible that something got bumped out of place or dust got somewhere it shouldn't have. Also, does accidentally brushing a finger against traces or chips/etc. make a difference? I tried to keep my hands on the edge of the board but it still managed to slide around a bit.

As for caps, what should I replace them with? There's a lot of information and choices out there, it gets confusing to someone just starting to learn.
