Hmm it's about time to upgrade your X3 ...
X3 0.9 was an early beta version launched TWO years ago! X3 is on on version
0.21.
When updating from this early pre-release version, you will need to follow also use
this convert script to update pages and settings to current release branch of X3.
It should work now, although you may need to wait for for up to 24 hours (doubtful you have to wait more than 1 hour). I had to update this old resource to use SSL.
The URL you have there, is an outdated resource, loading the X3 javascript from Amazon Cloudfront CDN (for ultra-fast loading). Now, we use the Cloudfront link directly:
