Did you make sure that your lens was secured tightly to your camera? Is it not turning on at all? I would refer to the troubleshooting page to see some quick solutions that might solve your problem. Apparently this is a common problem with this specific camera, however, if the camera is not turning on at all, I placed it in a bag of rice for a few days, then gently blow dried the camera and it turned back on! Hopefully this helps and I wasn't entirely lucky. Good luck bro!
I found this website that has an extensive list of different kinds of SD cards that are approved for the Nikon 1 AW 1, but I would just pick up a 2 GB SD card from walgreens or your local convenience store! https://support.nikonusa.com/app/answers...-memory-cards---nikon1-aw1
