So I tried to make a new 0.5.3 server.
I downloaded MCV and got 1.2.3 server files.
I copied the server files and eng lang from 0.5.3 to 1.2.3.
I put the 0.5.3 server files into main 1.2.3 directory and the lang into the lang sub folder.
Tried to run it and nothing happened.
Made a run.bat and this came up

Any help will be cool.
