I have exactly this problem too with my new computer. I can connect perfectly ingame with the offical launcher. But cannot with the GUI : "invalid account".
I noticed when i try to launch with ffxiv.exe i have this message : "Unable to launch application. Launch using the ffxivboot.exe (0)". I think this is the problem but don't know how to resolve it :(
