Outlook Outlook Error on upgrade

[Phototronics]

I'm upgrading from MS Office 2003 to 2010. The installation process informed me that in order to upgrade I would need to have Svc Pak 3 installed on my Win XP Professional installation. After the SP3 installtion I started getting the error Business Contact Manager There was a problem connecting to the database engine. To try gain, please click Retry. If problem persits, check Help. I went on to install Office 2010 thinking that would probably solve the problem but it did not. Retry comes up the the same error, the error comes back if I cancel and help is not much help. I seem to remember having this problem before on a previous upgrade but I don't recall the answer.
Any ideas?
Thanks for your help!

I understood all the instructions up to step six and I'm not sure what I'm supposed to type. When I select add it appears that I have two names already installed. Should I delete them both and add myself. I'm the only user of this computer and it looks like I'm setup as admin.
