I had been hacking (unsuccessfully) the old Beta client to run on the Live Servers so I simply re-installed it from the .dmg file (which I had kept). [Hey with Tera-byte disk drives one can be a pack-rat .]
That client patched with no problems, and last night I ran in Rohan (Norcrofts questing) for over 5 hours with zero crash problems!
So, if you still have the .dmg file from the Update 8 beta, simply re-install it and let it patch -- the patch does take "forever."
