I've been trying to set up a Magic World 2 server and, after many, many crashes, I finally decided I'd try to build one with all of the mods from scratch. So I installed a Forge server to a folder on my desktop (using the installer .jar), it successfully finished installing, and upon startup... it crashed. I'm definitely doing things correctly (I suspected that maybe there was a different method for a past version, so I watched a tutorial video for 1.6.4 and followed the instructions exactly even though it was identical to setting up a server for a newer version, and it still didn't work). The GUI for the server doesn't even come up. Keep in mind that this is with no mods.
I have no idea what caused the crash or how to fix it (I'm extremely Java illiterate), so I thought I'd come to you guys for help. Here's the log. Thank you so much in advance for your help, and I'm sorry if this is in the wrong section of the Forums (I don't make new threads very often), please correct me if it is and I'll move it to wherever.
