[Plugin: eShop] No tables?

When i install eShop 6.2.12 it doesn’t create any tables so on every page in the eShop admin I get errors. For example:

WordPress database error: [Table ‘MY_DB.wp_eshop_orders’ doesn’t exist]
SELECT checkid FROM wp_eshop_orders WHERE status=’Pending’ && edited < DATE_SUB(NOW(), INTERVAL 4 DAY)

Why is that?
