You need to go into your database and locate "drp_uc_affiliate2_users" you then go in (it can be a bit of a pain, because you need to look up affiliate and user id's)- but you can go in and change the UID/AID to 'move' the users to the correct uid as upline etc.. We had a similar problem, where it was remembering cookies and an admin had gone in and manually created a user account for a customer- and then this customer was getting all the admins commissions. lol Ooops.
