I received an email about an Introductory Offer ($19.95) for Windows Live OneCare for Beta version users. I've been using the Beta version for about 80 days and want to buy the full version. The email instructs you to remove the Beta version and follow the link in the email. I've done that but I can't get past the page where you enter credit card information. It may be because I didn't make a note of the Windows Live ID that I used when I downloaded the Beta version so I setup a new ID. Or it could be something else. Contacting MS via email has led nowhere except automated responses telling me to use the Help Center. Ideas?
