can’t login after upgrade to v2.3

I did an upgrade today of WP2.1 to 2.3

I need to say I did 2 stupid things: 1 I did not made a dbase backup and 2 I forgot to de-activate plugins before backup.

Now I can’t login to admin because I recieve notification my dbase needs an update but when I press continu I recieve an error:
WordPress database error: [Tabel ‘7627wpres.wp_categories’ doesn’t exist]
SELECT * FROM wp_categories ORDER BY cat_ID

WordPress database error: [Tabel ‘7627wpres.wp_post2cat’ doesn’t exist]
SELECT * FROM wp_post2cat

WordPress database error: [Tabel ‘7627wpres.wp_link2cat’ doesn’t exist]
SELECT * FROM wp_link2cat

When I go to phpMyAdmin I can see these tables are removed from the dbase.

What and where do I need to change (manual) to fix my issue? Please help
