Help with fixing this?

Forget the name of the mod, it seemed pretty popular though so I'm hoping someone knows it. (Harvester turret, etc) the harvester does no damage and shoots error signs so I feel as if I installed it wrong or it's being messed up by another mod but I don't know which one due to the fact I have about 100 hundred installed. Other turrets in the same mod do this as well but they still do damage. http://imgur.com/o39vtyy

The mod which the turrets are from is Rimsenal. I haven't had this problem yet but I hope I could help you.
