I can't play...

I installed Flash Party normally on my computer, but while it's loading, all of a sudden, I get this Warning saying, "Abnormal local resources detected, please download again." What does that mean? I can't play Flash Party all of a sudden, it makes me want to uninstall & install again. Is there a way to fix this, to get rid of the warning? Please update this game, so I can play it again on my computer. Thank you.
