I had just bought Windows Live OneCare and installed it correctly onto my computer. However, when I went to install it on my other computer and everything went fine except that it says that I only have 15 days left on my subscription and no prompt has come up to "Activate Again" like the display says after you input the product key. Help!
Open One Care, select "Subscribe" and when asked for a Live ID enter the Live ID and password used to activate the first computer. Your subscription status will be recognized and One Care will activate.
