[AMOS] - Help calculating SRMR fit statistic

#1
So I'm using AMOS which does not include SRMR as a fit statistic for my SEM model. There is a plugin that is supposed to do this for AMOS but it does not work when there is missing data in the data set. Anyone have any workarounds, know of a macro, or how to make the plugin work in user-friendly language (IBM site has been unhelpful)? I have 15 observed variables in my model so calculating by hand for the 5-6 different models I want to run would be beyond tedious.
