Query: Card Failed After 18 Months

I bought this card in July 2009 and initially it worked fine. It started hiccuping about six months later and that was a sign to back it up and keep backing it up. Now, my Canon PS SD970IS tells me there's a memory card error and can't read it. My computer can't read it either. Just e-mailed Kingston support and will see what remedies they offer. The card is supposed to come with lifetime warranty. I've had other Kingston memory products (SD, SDHC, RAM) and this is the first one that's not working. I wouldn't draw any overall conclusions about the company or all their products.
