Xsell and notifications problem

[mydssbin]

I just installed the Xsell mod and I am having problem theNotifications section.

 

Here is what I get only when I am logged in as a customer.

 

1105 - File '.\oscommerce\products_notifications.MYD' not found (Errcode: 2)

 

select count(*) as count from products_notifications where products_id = '42' and customers_id = '3'

 

[TEP STOP]

 

But When I am not logged in the notification frame works fine

 

Any ideas?

 

Thanks
