I followed the the PDF found on the wiki on how to set up your own server and did everything in there that it had me do. I got all the way to the point of actually running start.bat to get the server up and running. I noticed in the world.exe window it posts a few errors.
After it gets past that part, it just keeps repeating the error at the bottom of this image.
Any ideas on what I can do to fix this? I looked around here on the forums and on the wiki, but I didnt see anything that really stood out.
