Did you run the FTBinstall.bat or FTBinstall.sh if on Linux or Mac?

Try redownloading the pack, to me it looks like the download is not complete. I think you should also update your java to at least java 7, you are currently running java 6.

I only realized the cause of the crash afted asking for the crash report, and I was too slow to edit my post.

It crashes because Big Reactors is missing a required mod, and it looks like it's missing because for some reason it can't open/read the jar/zip file.

Try connecting to 127.0.0.1 or localhost and see if you can connect.
