You should be able to go to the checksoft site and log in with the same Id and password ***** you used when placing the order. Once you log in there should be a section for my account or my orders etc that will have the download available.
If you can't find it I can log into your computer remotely to find it for you. Or try to get you more detailed instructions but usually it's not hard to find once you know it's there
did you purchase it from avenquest directly ?
you would log in there at this page
the id should be your email address and you can use the little lost password ***** to get your password ***** you dont know it.
it is also sold by a bunch of other companies such as amazon
does the email say what company you purchased it from ?
if you do not know tell me who the email with the purchase number was sent from please
