When applying the full body morphs, what I do is to select a part of the figure, then at the top of the parameter dials, click the pull-down menu and select "BODY" to make sure you are not trying to apply the morph to a finger only.

As for your account at DAZ, if you are not the person they name, they have a place for you to click so you can correct the misidentification. Or, simply contact tech support and tell them about it.
