Converting from b2

Okay, I’ve installed WordPress and I did the b2-convert thing, but all my posts from my b2 account still don’t seem to be present. What step am I missing here…?
EDIT: I just realized there seems to be a bunch of errors that occur during the importing process (as follows):

Database error: [Duplicate column name ‘post_excerpt’]
ALTER TABLE wp_posts ADD COLUMN post_excerpt text NOT NULL;
Database error: [Duplicate column name ‘post_status’]
ALTER TABLE wp_posts ADD post_status ENUM(‘publish’,’draft’,’private’) NOT NULL, ADD comment_status ENUM(‘open’,’closed’) NOT NULL, ADD ping_status ENUM(‘open’,’closed’) NOT NULL, ADD post_password varchar(20) NOT NULL;
That went well! Now let’s clean up the b2 database structure a bit…
Database error: [Can’t DROP ‘ID’. Check that column/key exists]
ALTER TABLE wp_posts DROP INDEX ID
One down, two to go…
Database error: [Table ‘sinsanct_wp1.wp_settings’ doesn’t exist]
ALTER TABLE wp_settings DROP INDEX ID
So far so good.
Database error: [Can’t DROP ‘post_karma’. Check that column/key exists]
ALTER TABLE wp_posts DROP post_karma
Almost there…
Database error: [Can’t DROP ‘ID’. Check that column/key exists]
ALTER TABLE wp_users DROP INDEX ID

Ideas, anyone…?
