I'm having the same problem
I just donated to the aero glass project because I think its project and I want to remove the water mark.
I received the thank you letter stating that I needed to use the password specified with my paypal email to access your private site. The problem is there was no password in the email or any other email received.
I tried generating a password but when I enter my paypal email & zip it says it can't find my email address.
here is my paypal order info :
Transacion id : 7DP84977V24612216
Confirmation number: 7DP84977V24612216
please help.
Thanks
