I really figured out why the introduction animation wouldn't play on my computer screen:
I wasn't the Web Browser, it was this ActiveX program I used to have! Anyway, I uninstalled it and that solved my problem.
Anyway, if you have any program, software or whatever that is preventing you from seeing my cartoons, get rid of it. ActiveX is one example that may not let you see my cartoons. Finally, it's Macromedia Flash Player Version 6 or newer that you need to see the animations. Thank you for reading.
