help! turtle gui not opening and crafting kicks the player

I have a tekkit classic server in which when i try to craft a turtle, i leave the game with "java exception nullpointer" or something like that. Nothing shows up on the console when this happens. I then spawned in a turtle and it wouldnt let me open the gui, and on destroying it gave a metal post.
Is this some permission file i haven't found yet? or is it a more serious bug?
please help, and thanks to anyone who does
:)/>

Update: It now won't even let me have one in my inventory

Split into new topic.

Nothing we can do until we see a crash log.

If you don't have errors, tell us with witch version on computercraft you are running and list your addons

Try reinstalling CC along, and do that for your peripherals also.

There is no crash log, i just leave the game.

I'm sure this is a problem with my server too, as it happens to both my friend and me. I tried to update the version of CC in my server a while ago and then things started screwing up. After downgrading i then had to change the item id for a turtle in the config to stop it conflicting with railcraft structures.
Do config files automatically generate again if deleted? If so then im going to delete them and start again

Navigate to server folder/ForgeModLoader-0

Nevermind i fixed it by recreating the configs and changing turtle ID to 216

Thanks all for helping!
