Game Crash On A Single Server

I paid $30 for Minecraft, and the ONE SERVER I bought a rank on ( MC Central ) is continuously crashing after the words "Building Terrain" appear on screen. Oddly, this only appears on one server. I'm kinda mad because that's $45 gone to waste, if I can't fix it. I've tried research but I can't find anything updated. ALSO my brother is right next to me playing this server, so it is a problem just for me.
