Second door won't open (Ch2. Jackknife)

[^4AR^5200]

Is anyone else having the issue where the second emergency drain gate will not open? I got through the first one just fine but even though the second panel was activated, the door won't open. I don't know if this is a glitch in the game, or if it's something else. (Before anyone asks, yes I do own the game. I bought it a few hours ago because it was on sale and I've been wanting it for a while.)
