Database error

I installed the plugin correctly but when I go to the ToDo page in my Dashboard I get these messages:

WordPress database error: [Table ‘silentb_wrdp1.wp_pravin_todo’ doesn’t exist]
select * from wp_pravin_todo order by status ASC, date_due ASC

WordPress database error: [Table ‘silentb_wrdp1.wp_pravin_todo_options’ doesn’t exist]
SELECT show_limit FROM wp_pravin_todo_options LIMIT 1

WordPress database error: [Table ‘silentb_wrdp1.wp_pravin_todo_options’ doesn’t exist]
SELECT sort_order2 FROM wp_pravin_todo_options LIMIT 1

Seems like it’s something that’s wrong in the code of the plugin? Is there any way to fix it? Thanks in advance!
