[Server wont start]

So do I need to downgrade my client from 0.5.3 to 0.5.2 as well as the server?

[Server wont start]

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
