It has to be your PC I don't know what to tell you. I played here: http://www.coolmath-games.com/0-jump-n-bump

I know people that usually have problems running flash games is because of their browser, not their pc. Just make sure your browser is up to date, that it can run flash, and that flash is also enabled and up to date. I'm using chrome and it works for me, so if you're using something else maybe switch to that.

Yes, flashpoint is pretty well known now! This thread was 2 years old.
