I have a beautiful installation. It boots perfectly, audio works the 1 output and all 4 inputs! The display works too. There's only 1 problem, no 3rd party apps work. All the included apps work, like iPhoto and iTunes, but a game like Chuzzle, or anything else I download from the net, or even a mac game or app i buy at the apple store, won't launch. I click it, and it bounces once, then it sits and does nothing. Should I download another install disc? I don't care Tiger or Leopard, as long as it works. Or do I need some patch? Any help would be great! Thanks!

did you repair permissions?

No i haven't...

will try, thanks.

P.S. i am running OS X 10.4.1
