Me too. Though I've downloaded everything and can play the demo. But the actual game won't extract (recent version). It gets stuck on game.rgssa.3a when trying to run the .exe
For some reason, the displayed name staying as 'Prologue Demo' kept staying regardless of how many times it was changed until I exported it on another computer.
Along with that being fixed, the 29/06/19 version is now just an ordinary .zip - so while it's good you were able to resolve your issue with the previous archive format, hopefully this stops the issue happening to anyone else.
