Pete,
It seems your junk / spam filters are set too strong which is why the email never got into your inbox. Check the spam email folder or the spam settings for the domain name your email address is using and you should find the email / problem.
It may cause many other types of emails both from this forum and other websites to not get through to you as it does only contain one link and very little text. And it's sent with all the correct headers (techie stuff) to tell most decent spam systems that it's not spam and you did request it.
Give me a shout if you need me to help with that.
I look forward to your contribution - big or small.
