grrr for you.

Ok, I would go into the add/remove on the control panel and UNINSTALL / REMOVE the Java..everything Java.. then turn off the computer and restart to make sure it's clearly gone, then download Java again. Make sure you don't have anything else open, and if you have to have your security program disabled (I don't have a clue) then do that (it will tell you if you do need to do that.)

Are you on an IBM/PC or Mac? That might make a difference.
