I think the problem is with F & R ring set. The bot tries to attack with generator, but it gets stuck trying to use generator. The workaround for this I found was to
1) Unequip F&R
2) Equip some random rings
3) Start Demonbuddy (which will then recognize your current gear and save it)
4) Start the profile
5) Pause the profile
6) Equip F&R
Doing this will cause Demonbuddy to think that you are wearing two random rings that are not F&R (as long as you don't restart the Demonbuddy), and consequently it will not try to use generator unless you run out of resources. You will lose out 75% damage since you are not using generator, but better than nothing I guess.
I can't really say that this is viable solution for other classes, but for barb with BK set it is viable since you don't really need to generate resource.
