Are you saying that your whole rig crashes because a misconfigured mining software?  That's a bad situation.  There's a couple of things you can do.  Disable the rule that initiates the reboot sequence with the smart plugs until you can troubleshoot the problem.  When done, turn the rule back on.  Another thing you can do is hover your mouse over the stop button and as soon as AM kicks on the mining software click stop immediately... to keep the mining software from progressing to the point where it crashes the whole rig.  You can also disable the autostart miner from the managed miner or profit miner.

Hi,

If this is for the auto start of a miner after reboot, there is actually a setting in the Options dialog, Advanced section, that I added quite recently for this. "Delay auto start of miner after reboot".
