I just installed FFXI on a new Win10 PC. DirectPlay is enabled, and installation/updates seemed to go fine (I downloaded files & followed instructions here: Official site Windows install). I'm clicking 'run as admin' when I click the FFXI shortcut.
I'm able to login to POL and progress to the screen with the "Play" button. After hitting "Play," the opening ~5 minute cutscene plays. After the CS, I hit the OK button, which should lead me to the character selection screen, but the progress bar never reaches 100% -- around 60% it backs out and says the connection was terminated or is unavailable, with POL 512. This backs me out to POL, and shows POL 515.
This happened twice this morning with vanilla, and once with Windower4. I can connect just fine on my old Win7 PC.
Any ideas? I'm new to Win10 - not sure if there's something stupid I'm missing.
