Feedback layers freezing
I'm having a problem with a short AS2 lesson. For some reason, it's not working on all computers I've checked it from. Sometimes it gives a 404 error, sometimes it works perfectly, and sometimes the feedback layers will freeze and not advance. There is a title slide, 3 questions (only the 2nd question allows 2 attempts) and a results slide. I published it for the web and have included the link to that result below so that you can see the problems. I've also attached the raw file here in case that will help the helpers. Let me know what I've done wrong? Thanks!
