"Error establishing a database connection"

Hi,
I guess I messed up my database bad due to my attempt to install and reinstall a multisite network. The status right now is:

wp_5_posts: Table ‘domain_wrd1.wp_5_posts’ doesn’t exist
wp_5_comments: Table ‘domain_wrd1.wp_5_comments’ doesn’t exist
wp_5_links: Table ‘domain_wrd1.wp_5_links’ doesn’t exist
wp_5_options: Table ‘domain_wrd1.wp_5_options’ doesn’t exist
wp_5_postmeta: Table ‘domain_wrd1.wp_5_postmeta’ doesn’t exist
wp_5_terms: Table ‘domain_wrd1.wp_5_terms’ doesn’t exist
wp_5_term_taxonomy: Table ‘domain_wrd1.wp_5_term_taxonomy’ doesn’t exist
wp_5_term_relationships: Table ‘domain_wrd1.wp_5_term_relationships’ doesn’t exist
wp_5_commentmeta: Table ‘domain_wrd1.wp_5_commentmeta’ doesn’t exist

Followed by: “Error establishing a database connection“

I have followed the “Create a Netwok” instructions by the book.

When I’ve tried to uninstall the network I have followed this instruction. During my attempt to make a new installation I got this error message “An existing WordPress network was detected”.

Because of this I also deleted the “wp_5_…” tables in the DB. The single installation works if I replace the modified wp-config and .htacces-files with the original versions.

I’ve made a proper backup of my database before i started my installation. My host is Blue Host. What must I do to get the network installation back on track? Any help would be greatly appreciated.
