I have tried re-downloading the pack the launcher and even from different browsers, this is my favorite pack so if anyone has any ideas i'm all ears. Thank you for you help!

It looks like you somehow got an item id conflict between Railcraft and Computercraft. Try changing the elevator rail id from 207 to 212.

[jcubbear]

how?

[PBlock96]

Ok, go to where you installed the Technic launcher, then go into modpacks, then tekkit, then config, then railcraft, then, open up railcraft.cfg. On line 20 there is a config option that looks like this

   block.elevator=207

Change it to:

   block.elevator=212
