WaniKani Leech Trainer - Broken?

Hello, I’m having trouble getting this to work: https://greasyfork.org/en/scripts/35031-wanikani-leech-trainer. I can click on the button that brings up the trainer, and I can enter data, but when I hit the enter key to check my answer, nothing happens. Any ideas? Using Chrome on Windows7, and I tried turning off all extensions except Tampermonkey, to no effect. Thanks in advance for any help.
