Bought a copy from SE. it downloads, I install, and it starts, and boots into the updater. It takes a bit, but it updates, and loads. I exited the game to change some settings, go to relaunch it, and now the updater crashes, not allowing me to log back into the game.

I uninstalled the game, reinstalled it, let it update again, same problem. Checked and updated my graphics card driver and direct x. As far as I can tell the game actually works, it's just the updater that crashes.

My laptop settings:
Win7 x64
i3 2.40ghz
4gb ram
ATI Mobility HD5730 (I have a laptop with "switchable graphics", so this is the one I'm using with FFXIV, of course, the other one is a crappy integrated card.)

Any idea?
