I have been looking into this and understand what I have been doing wrong. What I have available to download are the files of the project, but I haven't posted a downloadable project that is actually playable. I'm very sorry about that, I didn't realize I was doing it wrong. However, now that I know how post a downloadable and playable project correctly, I have unfortunately been unable to produce one that works :(
I will keep working on trying to figure this out, I am really glad you brought this to my attention and I apologize that I don't have a good solution yet. Hopefully I will find the solution soon!
