David, I'm still having some trouble with this module: I just made a purchase, but had an incorrect CC number so received an error. I fixed the number and re-submitted the purchase, it worked the 2nd time. When I go to the accounts module there is only one item listed, and it's status is "Cancelled". Looking at the database, I can see that two users have been created in the Smith_Customer table referencing the same DNNLogin. (In fact, there are numerous duplicate DNNLogins in this table). I presume information is only being reported for one of these users.
Thanks,
Walter
