GEMMA M0

So I just got the Gemma M0 and working on this project but with only the 12 pixel Neopixel ring:

I got the Gemma recognized, Was able to add the board to arduino IDE as well as set the port. I then loaded the code up and it worked. My neopixels started lighting up. I changed some variables and loaded it a few times and it worked. Then I did it again, the loading bar started stalling and then it froze. I had to unplug it and now the port is missing and I don't know how to get it back. Can any one halp!

SOLVED. I ended up double clicking the reset button which did fixed the issue.

Thanks for taking the time to post an update with your solution blabberbytes! I'm glad to hear you got it working.
