Help with installation

help im confused!

I purchased an update of Norton secuirity for my computer in June 2011. I have since bought a new computer and have no idea how to get it onto my new computer.

The update I got was for 12 months, I have the email with all the confirmation details, prices etc.

When I go into my account it doesnt come up with my June purchase it only states I have the trail edition.

Also when I look for past purchases its blank.

As i have said I have the email still stating which edition, add ons, prices etc.

So im just wondering how to get it onto my new computer.

 

Any help would be much appreciated!

thanks
