Support Request: Server won't run?

Okay, I did that, as well as updated ModloaderMP from v2 to v2.1, but now im getting a different error message...
Also, it generated a config folder, a ModLoader text file, and a ModLoader.txt.lck
Heres the whole message -

Also, if you just have a plain minecraft_server.jar, nothing added to it, should it be able to run correctly? Because it doesn't for me...

Try deleting the .lck files. If it doesn't work, might be permission issues on the server folder.

The ModLoader.txt.lck goes away when the servers not trying to run...
What do you mean by permission issues in the folder?

Ahkay, I see what I was doing wrong-
I was running the minecraft_server.jar directly, I didnt have a startserver.bat thing to start it from.. Works fine now with that block break fix and everything
You can never trust those Youtube tutorials...
