Query: Went bad after 1 year

Had this card for about a year, and it worked well until 2 days ago. I had it in my Nikon D5000 and got the error, "Unable to Format Card. Card May Be Defective." Luckily I found a utility online to recover the pictures I had and I was able to re-format the card. It worked for another day and now I'm getting the error again.I tried cleaning the contacts w/ a cotton swab, and even tried inserting the card while locked & unlocked - didn't make a difference. Hopefully, theSanDisk 16GB Extreme - SDHC Class 10 High Performance memory card (SDSDX3-016G-P31, Retail Packaging) - NEW 30MB/s versionI just bought will last longer.
