The url listed in the magazine, and with a link from the disc is (without spaces)

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.
