Dataplug In won't inport

Hello

I am trying to load a data plug in which doesn't seem to import into my list of available data plugins.

When I try to reinstall the plugin I am asked if I want to overrite the existing plugin which leads me to believe it is loaded somewhere.

I am using the 2015 evaluation version of DIAdem (64 bit).  The data plugin I am trying to load works on other machines with copies of DIAdem juts not mine.  

Thanks
