Why won't Yahoo messenger work on Windows Vista?

How do you delete or reset the Content Advisor password on Windows Vista? I've found a solution for Windows XP but it doesn't work for Vista. It's starting to get annoying because it blocks everything involving AIM or Yahoo Messenger.

  Have you tried either of these? The following steps will remove any password set in the Internet Explorer Content Advisor and allow you to reset the program to its original state. 1) Click on Start and choose Run. 2) Type in RegEdit and select OK. 3) Now click on the little plus sign to the left of H_KEY_LOCAL_MACHINE. 4) Continue to drill down, always clicking on the plus sign at the left of the named key, through Software, Microsoft, Windows, Current Version and Policies. 5) Now click on the Ratings folder. 6) In the right pane of the RegEdit window, you'll see an icon called Key. Click on it and press Delete. 7) Next, choose Registry and then Exit to exit RegEdit.
