just returned my copy of FFXIV to amazon. Even when i met System requirement, it just won't work regardless of which method I tried to install the game. Spent the whole week trying to figure it out and no help from forum searches and of course zero help from Square-Enix... Maybe I'll wait for the PS3 version.
Edit: Oh and I also think I found the problem if anyone is having an issue with the "FFXIV.exe has stopped working" for anyone using the Mac Pro, I have upgraded from a Geforce 120 to see if that was the issue to a ATI 5770 and still get the error and tried installing all kinds of ways, through safe mode, doing a clean boot up of Windows 7, and even backing the drivers from 10.9 to 10.8 for ATI Catalyst and still no go. But through research, I think it is caused by the fact that it is the motherboard or the 2x Quad-cores in my setup. Square Enix technical support will not help what so ever.
