Since the completion of the site maintenance, I get 'loading' when trying to jump to play live chess page but never get past it.  Do I need to update something?

Can you please try a cache clear?

If you're unsure of how to do this, this link provides a step by step guide on how to clear the browser cache.

Please let me know if you're still having troubles :)

Yep, I should have mentioned that I had cleared the cache.  I reloaded my browser and java and the page shows up fine.
