I took your advice (ran ffxivboot64.exe in Win 8 compatibility mode (and administrative mode per other advice)) and I was finally able to get past the loading screen to Rak'tika. I immediately teleported to a known okay zone (Limsa Lominsa), but got the dx11 error during the loading screen for THAT zone. Any further attempt to log back in has resulted in a dx11 error popup and crash.

So...progress but still not playable. I'll keep tinkering...
