Crafting table III won't work

[megamanheroful]

Hi on my server when ever I try to make the crafting table III it will kick me and when I log back in the table is gone and the book and table are still in my inventory.And when I try to craft it the box where it turns up is flashing meaning half the time no one can even craft it.Also I tried to spawn it with the /give (username) 149 command but it said the id didn't exist so i spawned it with NEI which made me crash when I put it down.

server specs

• 4gb ram
  

comp

• 10gb ram
  
• pendium dual-core CPU
  

tekkit launcher

• 4gb ram
  

NOTE: I am playing on the same computer as the server and i sometimes have Skype open but I'm sure it isn't contributing to the problem.

Crafting table III was removed in Tekkit 3.1.1

Install Essentials (http://bit.ly/QdB0Nq) and use "/i 149 1" if 149 is the item id. Otherwise backup your world/server and the do a clean server install and put the world back in. :)
