I'm in exactly the same situation. My problems started on Friday on Ancestry.co.uk.
No links on Ancestry.co.uk are responding for me in Chrome. I've restarted my PC, cleared the cache and history, disabled extensions and it still won't respond.
IE9 on the same machine works fine. IE only ever gets used on my machine to test if Chrome has a problem, which in this case it does. I've even had to post this message using IE because the Post button won't respond in Chrome.
I've put in a support request to Ancestry to see if there's anything they can do to help.
