well, the key's to making the download center work are:
1) setting the store order summary to save the users ID to OrderUserID column of the orders table.
for express checkout, the store order summary behavior will be on the pp_confirm page.
double check your login page, double click the authenticate user behavior and go to the Session tab to double check the name of the session being created. make sure this is the session you have bound the OrderUserID column of the orders table to in the store order summary behavior.
2) in the recordset for the download center page, make sure that you are referring to the correct session variable.
getting the order history and download center page to work correctly all depends on using the correct session variable that is created by the login page.
if you continue to have a problem, I'll need to see the code on the login page, the pp_confirm page and order history / download center pages you created.
