I have a Panasonic Zs7, its been working fine, but lately every time I press The record button the message (Insert SD card again) comes up every time and the only way to get out of it is to turn off and restart again. I can take pictures but every time i press record I get the same message. I have tried taking the card out, and taking the battery out and reinserting but the same error messege comes up only when i press record. The contacts on both the battery and card seem fine. I am using A kingston SDHC card if that helps. any help, Thanks.
