Hi there. RGM is still in the not ready for use. It will crash and fail. The versions you see were released as more of a 'Sneak Preview", so it may work, for some and others, it may not.
However, one of the developers, Robert Colton, did recommend moving it to the ENIGMA-DEV folder, then build emake with CLI_ENABLE_SERVER=TRUE.
In the meantime, please continue using LGM until the Announcement is given......(which may be in December)
