Multi-line JTextPane: My SSCCE works, but not my reg. code . [LONG, sorry.]

Question

So, I'm trying to code this flash cards program, and it's not working. The problem is that, when I change the text of the JTextPane to have multiple lines, the text disappears, and my JTextPane acts like it's empty. I included my SSCCE as a comparison, because it works just fine. I hope you guys don't mind that I included all of the code for my Cards program, even the stuff that I know isn't relevant, but I'm at a loss, and it's bedtime, so I'm done editing for the night. If you guys can fix my code, feel free to use it for your own personal use (as a reward for having to deal with the irrelevant stuff). How do I get my text to appear when it has multiple lines?
PS I know my button listeners aren't like they should be. I'm going to fix them after I fix the JTextPane.
PPS If this breaks anyone's browser, I'm sorry, but I included a file that is format-dependent, so I had to include it as is. Also, I had to include tabs and not spaces because of the length limit.

No way anybody in their right mind is going to look at all that. Find the salient differences between your SCCE and your non-working code.I didn't think so, but it was worth a shot. I did my best to find it last night, but I just couldn't.

Dream well
JeanetteIt was midnight, and I had to wake up at 5:30, so that was true. I didn't really think it was going to work, but I was hoping.
Anyway, this can be locked too, I guess. I have an idea on how to find what's wrong.
