First open one from the stick. If that's good then your new phone card might be faulty or possibly they're not all really .jpeg's.

This might seem strange but are all devices either 32 or 64 bit? A mixture can cause this problem.

You can look up the specs for each. Chances are an old camera with a new computer or vice versa would cause the problem. Any other person reading this might want to know if Android, iPhone and some computer info.

Had to really dig deep after finding the processor of each, it appears your old one was 32 bit, new one 64 bit. This possibly has caused the problem as others have encountered it. I wouldn't trust a 3rd party converter. I'd like other comments on this, but consider taking the whole mess into your computer HD or SSD and back out rather than using the USB stick.
