Staring process goes until “success” - and crash! Trying to open in offline-mode - crash! I see no way to go back a version of MGP - my solution so far: I use Metagrid 4 - that lets me use some of my grids.
Moreover: its not possible to assign scene switch commands in the Metaserver 5.0 window. Record button turns red - and finish… good luck for repair!
