I have 'lost' my user account, but I have all the data backed up on an external hard drive. I want to know how to create a new user account which is linked to all my documents and emails and email settings. Can I do this or do I have to start again with email settings etc?

Background:
I was administrator on my pc as well as user.
I created a new admin account and changed my status to standard.
Then I was unable to load my user profile.
I have tried system restore at several different time points but always get a message that it did not restore due to 'unspecified error'.
I precisely followed the tutorial on this forum to fix "your user profile not loaded correctly..." but this did not solve my problem.
On C/users/sandra - I can see all my data.
But when I click on the icon for Sandra on the login screen, it goes to a generic profile.

Thanks in anticipation
Sandra
