SW hasn't been working for a lot of people going on 3 months now. So all I can say really is you're not alone. I'm cancelling mine at the end of the month. I've gotten one alert in the past 2 months, and I know for a fact that my score has changed many times. Plus, I've gotten 2 new credit cards with two inquiries and didn't get a single alert.
