Anguka,
I've tried using the script with an Australian address, and it's still working OK for me. For a moment, I thought Multimap might have made a change that broke my script!
I'm not sure what's going wrong for you. Please contact me by email (you'll find the address via the 'About Stephen Withers' link above), and tell me what browser you're using, and a street address that won't work for you. For privacy reasons, you might choose a 'fake' address such as that of a shop or post office. That's ok, as long as it is a genuine address. Please also attach the browse.cgi file that your browser is downloading.
