You'll need to use your computer and an SD card adapter. Choose, "Update your camera manually"
Is the SD card the same as you were having issues with the other camera? It's possible there is an issue with that particular card. Do a full (not Quick) format of the card in your computer. Download and install the manual update. Once done, go to preferences on the camera and scroll down to format. Format the card in the camera. Be sure when you format in your computer you choose exFAT.
If you still have issues, try a different card that has been formatted.

I personally use Samsung Pro and Lexar 1000X although they are not on the tested to work list.
You want to format the card in the camera regularly and occasionally do a FULL format in your computer. Do not store/delete individual files from the card. Always clear the card by performing a format in the camera before starting a shoot. Offload the media from the card when you are done.
Always keep your camera on the latest firmware update. If you have issues, preform a manual update using an adapter and your computer.
