How do I start a server

I'm having a little trouble setting up a server, whenever I click the start button, it stops and when I analyze it, it shows this:




My Server:



Please help me, because I really want to use servers with this mod, also this is for minecraft 1.8, and the mod version is 1.5.10.24-universal.

My forge version is: 11.14.1.1334

That's OpenComputers, not ComputerCraft. Please try asking over at their forums.
