Thanks for posting this on the forum.
The url listed in the magazine, and with a link from the disc is (without spaces)
http:// www. ulead.co.uk/ events/pi6register.htm
or click here
You should be able to click on this, fill out the simple form and then await an email from Ulead.
Alternatively, try this url (without spaces): http:// activity.ulead.com /uk/events/special_register/pi/register.htm or click here
This will provide you with the same form.
I've tested this and the page seems to be working without any errors, and I have since received the email from Ulead. This email contains a link, click on this to see your serial number.
