I'm sure many other people are having trouble with this as well, but the 1.6.4 packs are launching but not letting me create a new world. This is the error i'm getting.

I don't really get what she is talking about in the post what is the difference and what folders are the server and client config files in? Also btw I'm on a Mac

Bouncy Castle issue.
Apparently now a vanilla issue.
Formerly was "solved" by downloading the server configs and replacing the client configs with the server configs.
I don't know if that works with the new issue however.

Please note, the person who had this same issue on that thread solved the problem by changing world seeds and making a new world.
 
I have been having the exact same error symptoms since the implementation of the 1.6 packs, but not the same log. I think that the error is caused by libraries not being loaded, because the files are there.

Not the same as java.lang.NoClassDefFoundError: org/bouncycastle/jce/provider/BouncyCastleProvider

I'm no expert on linux, but try using the jre only not the jdk version of Java. I know the jre is in the jdk, but minecraft might not play well with it that way.

I tried that before and it did not fix the problem. Also tried switching away from openjdk and it stopped letting me use the pastebin button on the launcher, although I did not go back to openjdk.

The error is not from bouncycastle/jce, its from bouncycastle/crypto. I don't know where the libraries folder for ftb is but it could be caused by it not downloading or loading the bouncycastle jarfile. Also when I booted into windows it ran fine, so it caused by something in linux.
