Find the folder with your V4/M4/K4 cr2's, in it you will see a number of DS scripts, these are the powerloader scripts for each gen 4 cr2, if you don't want powerloader then just delete them.

This might fix your problem, but then again it might not, the EXP system DAZ uses with the gen 4's is touchy, check your drives and make sure you only have 1 each of "!DAZ/Victoria 4","!DAZ/Michael 4" & "!DAZ/The Kids 4", more than one and they interfere with each other.
