Southern Mexico glitch[s]?

[Phoenix_Death]

Ok, I got through the Thailand glitch with no problem.

But now I'm way far into the Southern Mexico level. I'm past the first pool of blue kill-you-if-you-touch-it liquid, and I'm at the second pool.

I killed the creature, climbed the ledges to the top of the support column, shot it down, and crossed to the dragon puzzle. I started to burn away the stuff, and the game randomly decided to step away from the puzzle and put me back at the beginning of the bridge I jumped to. And it put the column back up.

So, I shot it back down. But then my entire screen turned like, a baby blue color, and I couldn't do anything. So I re-loaded the game, and re-shot the column[again]. This time it worked. So I went back to the puzzle, burned away the stuff, and started to try and complete it.

I had to go for a while, so I left the game on, and when I came back, the game would not let me finish the puzzle. I stand right in front of it and hit -, but nothing happens. So, I went back to the first room and pulled out the PDA, it said that I had to shoot the column down. Even though it was already shot down. So I went back to the other room, and the column was already on the ground.

So I pulled out the PDA again, and it read "I should explore the area beyond the doors that just opened."
But, the problem with that is, that's what it said when I solved the statue puzzle, before I even got to the dragon puzzle in the first place.

So, all in all;
I can't solve the dragon puzzle.
My PDA says to do something I've already done
And, I have absolutely no idea what to do, or what is wrong.

Oh, and this might help, I have the Wii version.

Help?
