Ok, so I've been messing with my Java settings because I got scared because of what I read about the security issue. I wish I hadn't messed with them because now I can't listen to Grooveshark anymore.
I went into applications - Utilities - Java prefs and unclicked two boxes to completely disable Java. I decided I wanted to enable them again so I can have a better experience. Now when I got to Apps, utilities, etc., there is no Java prefs.
Any ideas? I really need to leave well enough alone. I'm always messing under the hood. I need to stop that.
