Whenever I try to click on a link in my Microsoft Outlook 2010 email, I get a "Class Not Registered" error message? How do I fix this without losing all the bookmarks I've accumulated over the years?

What kind of link it that (what file extension does it have)?

This usually means that you do not have an application set on Windows to handle this file type.
