Error while changing WP single site to multisite installation

Hi all!
I was trying to change my WP installation to multisite installation on LOCAL HOST following following steps:

1. Adding following line to wp-config.php file above the /* That’s all, stop editing! Happy blogging. */ line.
define( ‘WP_ALLOW_MULTISITE’, true );

2. Completed Multisite installation after deactivating all the plugins.

3. Added following lines (given by WP itself) to wp-config.php file:
define(‘SUBDOMAIN_INSTALL’, false);
define(‘DOMAIN_CURRENT_SITE’, ‘127.0.0.1’);
define(‘PATH_CURRENT_SITE’, ‘/wp/’);
define(‘SITE_ID_CURRENT_SITE’, 1);
define(‘BLOG_ID_CURRENT_SITE’, 1);

4. Added following lines (given by WP itself) to .htaccess file:
# BEGIN WordPress

RewriteEngine On
RewriteBase /wp/
RewriteRule ^index\.php$ – [L]

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ – [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]

# END WordPress

5. Now I get following error:
Connection to database could not be stablished.

The error page itself directed me to repair my database by adding following extra line to wp-config.php file:
define(‘WP_ALLOW_REPAIR’, true);

6. After reparing (and optimizing) my tables using above step, I was issued instruction that “Some database problems could not be repaired. Please copy-and-paste the following list of errors to the WordPress support forums to get additional assistance.”

wp_t7y3zsxy57_1_posts: Table ‘wpdatabase.wp_t7y3zsxy57_1_posts’ doesn’t exist
wp_t7y3zsxy57_1_comments: Table ‘wpdatabase.wp_t7y3zsxy57_1_comments’ doesn’t exist

wp_t7y3zsxy57_1_commentmeta: Table ‘wpdatabase.wp_t7y3zsxy57_1_commentmeta’ doesn’t exist

So here I am! Can anyone put my nose in right direction please?

Cheers!
