Sandisk 16gb SDHC recognized on panasonic tv but not on any PCs --- Help please


I have bought a Sandisk SDHC ultra 16 gb card for nikon d5100 camera. After taking 200 photos, it complains that card cannot be read.

None of my computers can browse the memory card on a PC…but my panasonic tv SDHC slot can display the images on tv…

Please help me retrieve / copy images out for printing.
