Go to your starmade directory, and delete everything except the folders:
/blueprints
/server-database
Now get the latest build from
here. (Use the one with latest timestamp, usually the last one in the list)
Extract it in the /starmade subfolder (the place /blueprints and /server-database are)
This should bring it back to a working state.
For an extra secure way,
that comes out without touching the current folder
(and not doing any more damage in case of any mistake):
Follow
this guide.
And Copy in the /blueprints and /server-database folder to
C:\starmade\StarMade before starting.
