SDcards that doesn't work with Pocket Cinema Camera?

I have just recieved my new camera and I needed to try it out immediately, but when i plugged in my SanDisk Ultra 16GB no SD was found. Do i need to buy a new SD or is there anything I need to do?

Officially supported cards are listed here:

If you want to shoot RAW the only card that currently works is the 64GB SanDisk Extreme Pro 95MB/s

You also need to format the card in your computer first. ExFAT or HFS+.
