What program did you use to unpack the fpk files? Specifically, since I have Vista 64, what version? Since PAKBuild 2.14 doesn't even recognize them as usable files. nevermind, figured it out. Now to test on SVN4192. It worked. It was the c2c.fpk (for me anyway), as that was the only one I unpacked. It was done by staring a save game from 3564 and no other prep work (I even kept the BTS cache).
