DB error after instal

I have recently installed WP. After instal, I browsed for a template, uploaded it, and then tried to input text as a text. I received a DB error stating a table did not exist.

I am not an expert (hardly above novice- meager understanding of what SQL command should look like) and I was wondering if anyone in here could point me either to the correct install table syntax for the missing table???

Here is what the error looked like:

<<< WordPress database error: [Table ‘MYDB_wrdp1.wp_post2cat’ doesn’t exist]?SELECT DISTINCT posts.ID, posts.post_title FROM wp_posts posts, wp_post2cat post2cat WHERE posts.ID <> 1 AND posts.post_status = ‘publish’ AND posts.ID = post2cat.post_id AND post2cat.category_id IN(1) ORDER BY posts.post_date DESC LIMIT 5>>

Can anyone help me with this insert???
