Hey Karl, it does help. I had been testing AC14-RC1 that had been working fine prior to installing the official version. Perhaps removing that version may have contributed to the issue I guess.
So if I understand you correctly, I should re-install AC13 from the original disc, then update via 'check for updates,' after which re-attempt the install of BM14.
Thanks for the assistance! Scott
