I assume you are seeing the 104 days within the main OneCare interface. You should not be prompted for renewal until 30 days or so before expiration. When you reinstalled Equipt, did you activate with the same LiveID that was used to activate originally?
If your subscription to OneCare shows incorrect or expired in OneCare
- Check your PC date and time.
- Check your subscription status by logging in with your subscription LiveID at http://billing.microsoft.com
- Confirm that this is the same LiveID shown to be the Subscription ID in OneCare - Help/About…
- Open OneCare and click "Check for Updates" to have OneCare check for updated credentials
If your subscription is correctly shown at the Billing site, but incorrect in OneCare and your PC date and time are correct, please contact support.
