Thanks in advance for your help.

I had the same problem as most, LW shut down on launch, but I followed the instructions about the java deal and it now opens. When it opens, it has that screen that gives you the option to download Pro or click Later. While this pop up is open, LW goes through all the motions, I get full green bars, and the cursor starts blinking in the search field. However, whatever button I click on in the popup at that point (Later, Yes, Why) causes the popup to disappear as it should, but the search field cursor disappears and the mouse cursor starts pinwheeling. LW completely locks up and I have to Force Quit. Any ideas? I've already run Disc Utility has been advised.
