You're getting an ID conflict, which shouldn't happen at all. You've altered your .technicpack in some way. I'm guessing you've tried adding another mod? You're going to have to fix that ID conflict if you want it to work.

This has happened to quite a few people actually. I've seen 3 or more posts with the exact same error, so i dont think he changed it. Maybe it's an error when updating, that the launcher won't update Railcraft configs?

[Cheap Shot]

Yeah, and they've all probably messed with their folders or tried to install new mods. It's really not that uncommon. People are trying to shove in all kinds of other mods all the time without having any idea of what's involved. They shouldn't be getting that conflict at all if they weren't because then every single person would be. You follow?

I also received this error it was when I used the Latest in development build and then reverted to the recommended build. How I fixed it was backed up my saves and removed the technicssp folder completely and re downloaded the recommended build.

[Cheap Shot]

Yeah that too. You can't just roll back from the dev build. You need to back everything up or be prepared to reinstall.
