Link between Accounts and Contacts

I have created all the records for my accounts in Business Contact Manager as well as all my Business Contacts in Business Contacts Menager. When I set them up I chose a primary contact in Accounts from by Business Contacts and also added a number of Business Contacts to the Account record as I assumed that is how it was supposed to work. Now when I go to have a look at my Account records there is no Primary or additional business contacts Business Contacts showing. Further if I try to click on the box to add these contacts nothing happens. It appears as though the link between Accounts and Contacts has been lost. Also if I try to add a new contact to the file, I enter the name and address & try to save I get a box that says: "Teh File As field for this contact is empty. You may not have entered a name or a company. Do you want to save this Contact with an empty File As field?  Yes/No" If I say Yes it saves the record but without the name. Is there any way I can repair this problem? Do I need to re-load Outlook? If I do re-load Outlook will I lose the info I have already entered?
