Encountered an unexpected exception RuntimeException

Usually when I forget I have a server running and I try to launch one it comes up with the runtime exception, except that it has an added "Port already being used 25565" or something. Check you aren't trying to run two at the same time.

Also, you would get more help in tech support. I don't think many tech support people come to general chat.

Is there a particular reason you want 5.2.0? If not I suggest you try 5.3.2 working well for me. I have copied my world saves all the way through the patches and all is good with 5.3.2 Well as far as I can tell anyway still pretty new to it all.
