You can send the projects to contact@hyperpad.com
What was the issue with the files Robinson fixed for you? Robinson is a member of the hyperPad team, so if he's fixed the file for you but you can't access it then thats a different issue. Sending it to contact@hyperpad.com would end up being forwarded to him again.
As for account deletion, even if you deleted the account after the fact, it doesn't make a difference, as the issue was already done when you logged into an account trying to open a file from an older account. Even if that account no longer exists, the permissions are still associated with another account.
This is why we tell people not to make a new user account if they plan to access their old files as it creates a bit of a headache due to security.
