Ok, I have a different problem than everyone else here with the arcade. The game "Simpsons Shooter" works fine, and I submitted my score. However, when I should have gotten first place, i only got fourth. My score tied with first, and I had a second less as far as time. I should be first, no?
I'm going to ask again: Do you have the latest Macromedia? Click the link on the bottom of the arcade. Maybe yours is outdated or something. All I know is everyone doesn't have that problem, so it has to be something on your side. I don't have the problem (sadly) so I can't tell you what the problem is.
I'll see what version of Macromedia I have and see how that goes.
Funny thing is though, if I get a score lower than the highest it registers. It seems to be when I beat the score that I get the problem.
