I downloaded a really old MUD codebase called WolfMUD. It was written in JAVA of course, the problem is that I used it the other week and there were no problems at all, everything was just fine, I deleted and re-downloaded it and the server errors, and I can't fix it. It's completely random.
I have uploaded a screenshot of the error and the actual codebase. I would be so very thankful is someone could have a look and see if they can figure out the problem.
