I don't know what just happened. I'm typing from a different computer now, but I was downloading MP3's on MY computer and a weird half japanese message appeared. Lots of beeping. In English it told me I had to restart my imac, and, indeed I did, as nothing else worked. Now it won't restart and the computer has reverted back to Code, which I don't know beans about holy crap this stinks, someone please. ANYONE! HELP ME!
