WordPress database error since I upgrade

Hi,

Today I Upgrade to WordPress 2.1.3 and since that time, my blog has a problem with links and categories…

In the page WRITE POST, all my categories are gone and appear the following text:

WordPress database error: [Unknown column ‘link_count’ in ‘where clause’]
SELECT cat_ID FROM wp_categories WHERE category_parent = 0 AND ( link_count = 0 OR category_count != 0 OR ( link_count = 0 AND category_count = 0 ) ) ORDER BY category_count DESC

The similar error apperars in the blogroll page…

Please help me with this problem… I don’t know what to do… Should I downgrade to the last version or I need to activate or desactivate some preferences in my current version (2.1.3) to the post categories and links work properly.

Thanks You All
