All P2 card files have become corrupted on one whole card after offloading onto a hard drive.Cannot play, no duration, only icons for clips left. Clip repair does not work. Files on hard drive seem OK except one has no audio. May not have write-protected card before off-loading. URGENT. About to leave for long project. Could card be damaged? Panny updated Firmware since I bought last year, but haven't downloaded any helpful apps. Thanks, John, NYC
