So I don't recommend anyone do this unless they have no choice, but I was able to fix mine.
I saw a screw on the side of the leg and thought that maybe it was holding the joint in place because the more I looked at it, the more it seemed like it was the entire joint that was backwards, not just the foot.
Anyway, besides a minor heart attack after I removed the screw and then pulled the piece off, which sent it and the joint flying, plus almost making me hit my desk and causing the black screw to fall onto my black carpet......it looks great now!
