I mad a video presentation in cyber link power director 14 ultra, and now when trying to trim a few seconds off the end I get an annoying message

Hello, recently I had to make a video for a banquet, So I bought cyber link power director 14 ultra because it had a great Black Friday deal and I just needed a new video editing software. So I made my video and I presented it yesterday at the banquet, everything went very well (everyone liked the video) but I realized there was a typo, fuuuuck I thought to myself, not only was it a typo but it was of someone's name. So I open the video in cyber link and I get this shitty message EVERYTHING WAS FINE BEFORE! And when playing back the video in the editor it stops at the same fucking point with that same fucking message! I can't fix my problem because Cyberlink is being so childish, I need to get this on a disc (preferably completely finished) to hand out to the parents in at the most 2 days, I've already put easily over 48 hours making this video, and this is really just pissing me off. Please help
