Error -2146697203

How's that for an error number?

Context:
I recently had to perform a system restore on my computer. I've never encountered this error before, and am playing XIV on PC (running Windows 7). After trying to start the launcher, I get the "checking updater/launcher version" message, followed immediately by the launcher screen, completely white (news and login bars not loading, etc.), with the aforementioned error message displayed.
A screencap:

I've tried:

• Uninstalling and reinstalling FFXIV
• Deleting the "My Games\My Documents\FINAL FANTASY XIV - A Realm Reborn" folder.
• Restarting the computer.
• Based on having been told that the launcher runs through IE: in Internet Explorer's Internet Options, in LAN Settings checking "Automatically detect settings", and in Advanced -> Settings checking "Allow software to run or install even if the signature is invalid."

None of which have worked, or produced any apparent change in the launcher's behavior.

It is basically a browser message that connectivity was lost during the download of the page. There's a recently discovered issue with encryption support--enable them under the advanced settings for your browser/internet. Even if you have blocked IE through WinSxS, it's settings are still in play with the launcher, since it is built on MSIE. You can still get at it through the Internet Options snap-in in Control Panel (or running inetcpl.cpl from the run/search box). It's under the Advanced tab, scroll down to the bottom of the list. Last week, SE put a notice up about a recent Windows Update that is resetting the options and causing issues, but it isn't necessarily limited to IE 11:
