A system error has occurred: -2146697211

I get the error in the title on the FFXIV launch page. Running Windows 7 64-bit.

Internet is ok (I can get here for example). Tried on multiple PCs. None can login.

The launch page comes up and looks like:

See the missing part on the right? No place for user, password, security token to be entered. After about 2-3 minutes, a window pops up with the following message:
A system error has occurred: -2146697211

Anyone? Bueller? Bueller?

Still happening intermittently over the past week.

I got that once after entering my login info....it seems to be related to something with Windows and .NET issues. I've found I've been able to avoid it by waiting a few moments after entering login info, but since you can't even do that, I'd suggest a reinstall.
