I first learned this a long time ago and decided to relearn it, so I have used this cube before and solved it just fine. However, learning this time around, I am having a lot of trouble in the last row, getting the middle pieces lined up. No matter how many times I do the steps, I either get 0,1, or 2 pieces lined up, but never all of them. I've watched many videos, and they don't have an answer for me.

Is it broken or am I just stupid? Please advise.
