Cannot login or download after purchase

Hi

I am unable to login or download EasyDiscuss since purchasing the extension in December last year. See here - previous question

I have today created a new login, but I receive no confirmation as to what my username is either. Is username = email address?

Could you please link my purchase from last year with this new account?

Please do not close this question until I confirm that I can login and download.

Thank you
T'Anne
