Launcher script error

Hi, I am getting the following error when I try to launch the game. This started occurring after launching the game successfully a few minute earlier and then getting BSOD this morning. This is the first time I've tried logging on since Friday night. I am on a PC running Windows 10 and have a Steam license. Any help would be sincerely appreciated! I would prefer not to reinstall the game if at all possible.

An error has occurred in the script on this page.
Line: 1
Char: 1
Error: Invalid character
Code: 0
URL: https://launcher.finalfantasyxiv.com...1187.bundle.js

Just coming back to post this troubleshooting guide I found in another thread. Following these steps seems to have fixed the issue.

Open Internet Explorer, then open the "Tools" setting, go to "Internet Options" and adjust the following settings:

- Under the "General" tab, please delete ALL browser history.
- Under the "Security" tab, please move the slider to the lowest possible settings or no higher than "Medium"
- Under the "Privacy" tab, click “Advanced” and select ‘Accept’ under both First Party and Third Party Cookies.
- Under the "Advanced" tab, please make sure that "Allow software to run or install even if signature is invalid" is CHECKED.
- Make sure that all SSL and TLS (EXCEPT SSL 3.0) are CHECKED. [SSL 3.0 should be UNCHECKED]
- Hit "Apply" to save the settings, and then "OK, to close the Internet Options menu.
- Right-Click on the FFXIV launcher icon and select "Properties"
- Hit "Apply", then "OK" to save the changes.
- Please RESTART your PC now. Once your PC has been restarted, Right-Click the FFXIV launcher icon once more and select "Run as Administrator"
