1.6.4 packs didn't much care for Java 8. If I remember right. There is a file somewhere that might fix it. Just can't remember where. Could be forges sight.

Might also want to uninstall all the version of java you have and install the most recent 64bit version. Java 8 update 51 by the looks of it.

(I used to have MCaffee installed. It loved installing software updates I didn't need. Then not unistalling the old versions. Took me awhile to turn that off.)

Yeah that pack you tried to run is using Forge 965, which won't work on Java 8. I don't know why FTB hasn't either thrown in a patch or updated them to the last Forge version for 1.6.4 that worked properly.
