Error In Transferring Special Load

I keep getting an error that reads, "Error in transferring special load". I'm not sure what this is or how to really solve it. I'm running a linear dynamic random vibration analysis using a base excitation of .01g^2/Hz on the downward plane of my box. The file is fairly large, so that may be getting in the way of it doing whatever it is trying to do. Any help would be appreciated.
