The extended warranty runs concurrently with the factory warranty for the first two years, but the good news is that the extended warranty has a provision for selling it back. I bought one, then realized it was a mistake and sold it back. If you don't sell it back within the first 30 days, you don't get all your money back, but at less than a year you will get most of it (I don't recall the calculations for selling it back after more than 30 days). The sooner you do it the better for you. Sorry to hear of your misfortune.
