New install problems

[Mr_T]

Hi, I've just installed OS commerce on a Windows server. It's a fantastic product! Thanks!

 

However, I'm getting the following errors and wondered if anyone could help?

 

On the Main Admin Screen:

1054 - Unknown column 'shipping_cost' in 'field list'



select orders_id, customers_name, date_purchased, orders_status, shipping_cost from orders order by orders_id DESC limit 5

 

Updating an order's status:

Warning: mail() [function.mail]: SMTP server response: 451 See http://pobox.com/~djb/docs/smtplf.html. in E:hshomeevolutiotshirts247.comadminincludesclassesemail.php on line 460

Thanks!
