Need Server Help!

[Gamerfreak]

I am not sure where to post this so I have posted it here, I was just playing on my tekkit 3.1.3 server and when I placed a redstone engine down (to use to power my wooden transport pipe) it began to crash the server. I had just powered it with a redstone torch and then boom it crashes. This is what the cmd says "

What do I do to fix this?

Maybe the server isnt updated to that version, Or you just need to reinstall the server.
