Good to know I'm not the only one. I sent an e-mail to CS right before posting here, so that's off and runnin'.
I just tried degassing, taking the reg off, the putting it back on, re-gassing, and the Operating Pressure was still at, or very close to 0.
Obviously a bummer, but I have faith in the CS team; I've had nothing but good interaction with them in the past. This regulator didn't even last 1 full day.
