Almost nothing seems to be working! Youtube videos only show up as black boxes, games like on MiniClip and ArmorGames don't show up, picture editing sites such as Picnik don't work and almost all my programs "quit unexpectedly"! HELP!! Some of the applications that don't work are: iTunes, Pages, Skype, Microsoft Messenger, aMSN and iPhoto. It's a real pain... what can I do?! I tried clearing my caches already, and reloading sites doesn't work. I need help ASAP!
