Script error?

[Enkidoh]

I'm getting a similar script error, except it shows a white screen with some text stating about server maintenance and 'to try again later'. And reloading the launcher does nothing, neither does clicking 'no' on the prompt, it still throws up the script error. I suspect Internet Explorer is at fault, as the launcher uses IE at it's core, so if the launcher kablooies it's probably IE acting up again.

EDIT: okay after a google search led me back to a past forum post with a similar problem, it seems the issue may be IE's security settings have changed, plus the cache needs clearing (Browsing history/cookies/temporary internet files). I've since followed that advice and done that but I haven't yet checked to see if it solves my particular issue by loading up FFXIV. Fingers crossed though.
