"Your miner was restarted automatically after a sudden stop"

gud

I'm all of a sudden getting a "Your miner was restarted automatically after a sudden stop" error on a third computer after working out fine on two other computers.

I'm using MacMiner 1.5.31 on an iMac 27" Retina. I've gone in and deleted ltcurls.conf and reentered it carefully from both the GPU Miner and the Main console windows as well as manually (and no curly quotes either). No luck.
