Does the power have someplace to go (batbox, MFE, etc)? Power won't flow unless it has a destination. If it does have someplace to go, try breaking a cable and replacing it. Sometimes the e-Net stops sending energy and breaking a cable and replacing it will reset it.
Like I said, I thought it may have been due to improper cable placement so I redid the cables several times over, in-fact I even watched a tutorial just to be sure. (and yes, the power has somewhere to go)
