I can see images on "playback" on the camera, but they are missing when I download!
Plenty of memory left on the 32 GB card.
Most of the images are downloaded, but none after a point.
Tried erasing some images in the camera and then downloading but all later images still missing.
Can you download images while camera is connected to your computer user USB?
If not - pull the card out, use utility like "Win32 Disk Imager" to make exact image of the card (so you can always restore it), and use recovery utility like PhotoRec to recover images.
