omg. I have some problems with my macbook right now. 1. I Can't Logout/Restart blah it always gives me the message that some kind of app is blocking the macbook from doing so (can be Finder or Mplayer or anything) 2. This started happening when I couldn't play AVI files anymore ( IN NO MEDIA PLAYER, I tried mplayer , VLC , Quicktime ... they just don'T play it...) 3. This all started happening when my VLC remote on my iPhone crashed... I wass just playing a AVI, and i was about to switch to the next one, then VLC remote crashed and since then 1 and 2 started happening... Do you guys have ANY ideas what this could be?
