windows xp professional user accounts

[digitalnature]

Hello,
I have a simple question but very complicated for me.I need to download software from HP,the only way that I was to download the software was to create a new user account, which I did and the software downloaded, but what happened is that my administrator account disappeared which is were I have all of my documents, pictures etc. I could not figure out how to keep my administrator account and a new user account, so I finally did a system restore which deleted the new user account and gave me back my administrator account and now I don't have the software I downloaded anymore.

What is the best way to solve this problem?

Thank you for any help
