Randomizing

I can’t make the plugin Randomize work.
Have this error:

WordPress database error: [Table ‘woldadb.wp_Randomize’ doesn’t exist]
SELECT posted FROM wp_Randomize ORDER BY posted ASC

WordPress database error: [Table ‘woldadb.wp_Randomize’ doesn’t exist]
SELECT posted FROM wp_Randomize ORDER BY posted DESC

Further, I get this error text when trying to create a new category:

WordPress database error: [Table ‘woldadb.wp_Randomize’ doesn’t exist]
SELECT id FROM wp_Randomize
No Randomize entries found… – enter some data using the form below…

And when I fill in an entrie:

WordPress database error: [You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ”images” at line 1]
INSERT INTO wp_Randomize (category_id, posted, random_string) values (‘images’, now()), ‘images’

Doh! Wasn’t inserted…

Also, 5 categories are supposed to show when having installed the plugin, but none show.

Help would be appreciated.
