Site conversion and user change problem

[LDiCesare]

After the site conversion, I've been unable to log in as LDiCesare. I may have forgotten my password, I may have registered here with an old email that's no longer valid, but whatever the reason, I can no longer log in as LDiCesare. I sent a mail to the address shown when you try and can't log in, but got no answer.
Is it possible to have my old account back or must I stick to this new one?

Were your login and display name different? If so, please see this notice:

If they were the same, please send me a pm so we can sort it out.
