If you lose or forgot your Project Express password, you can retrieve it by clicking the Account Information button and choosing "Forgot Password". Follow the instructions for resetting a Project Express password. You will need to verify that the e-mail address is yours.
Even though your user name is your e-mail address, files are not sent through e-mail, they are only accessible through the Project Express interface.
On Center Software personnel cannot verify if you have a Project Express account or provide your login credentials.
