I changed my sd card as the voice kept basically saying sd card not working. Reformatted holding the wifi button, not working, the camera now doesn't record at all and doesn't allow the wifi to work. Can't down load the software dierectly to the sd card. In need of some desperate help. Feel like I have to start from scratch. Any advice on how to do this as I've continually had problems, contacted the help desk directly on three occasions and had no answer. Really need some advice on how to get this all started again as it's driving me to distraction.
