Reinstall technic (so you have all the mods)
Find the config file for the teleport pipes
Change the block ids for teleport pipes to something else (preferably something not used by another mod already)
Open your world
The teleport pipes should have either disappeared or changed into another block. *
The next steps are optional, but they are advised.
If they have changed into new blocks, remove those blocks.
If you have removed all the blocks, reset the teleport pipes config file (this is doe bu deleong it and relaunching technic)
If they have disappeared, try placing blocks where they were. If you can, reset the config file.
Open your world. *
It should be fixed.
