I suggest you delete all the previous sub folders from the server folder (that includes the 2 batch files and hidden sub folders) and then re download the MSM and extract it to your server folder. If it still does not work let me know.
It still does not seem to work, for a bit better of detail on what is happening: I can open the .bat just fine and edit settings but once I actually select 1 to launch the server it just exits the .bat and nothing else happens.
