i have read this through and it looks like you need to perform a reset on your cam.
Have you backed up the images onto a pc or extra card ?
i would take the batterys out and leave it for around 36 hours with no power. This will send the camera back to default settings when you put the batteries back in and of course you will not loose the photos on the card !
If this doesnt work for you you may wish to get back in touch.
