mysql database reads old customers

[smart]

I am using mosCommerce updated a mysql that had old customers from osc website.

 

 

When I login name and password I the get an other customers

 

The only part of the website that is not working the clients email address do not link up with the correct information.

 

It may be a data base problem?

 

I am unsure?

 

Thanks
