Install fails when I attempt to use non-standard talbe names

I’ve been getting some interesting errors when modifying my wp-config.php file to use non-standard table name prefixes. I get the following message when I attempt to install:

“Fatal Error
If your blog does not display, please contact the owner of this site.

If you are the owner of this site please check that MySQL is running properly and all tables are error free.

Database Tables Missing.
Database tables are missing. This means that MySQL is either not running, WPMU was not installed properly, or someone deleted wpw1Kikey_site. You really should look at your database now.

What do I do now?
Read the bug report page. Some of the guidelines there may help you figure out what went wrong.
If you’re still stuck with this message, then check that your database contains the following tables:
wpw1Kikey_blogs
wpw1Kikey_users
wpw1Kikey_usermeta
wpw1Kikey_site
wpw1Kikey_sitemeta
wpw1Kikey_sitecategories
If you suspect a problem please report it to the support forums but you must include the information asked for in the WPMU bug reporting guidelines!

“

Have you ever experienced this and can you tell me what you did to trouble shoot it. I have plenty of other information, but it would most likely be best to get some back on forth going so I don’t throw a bunch of crap at you that doesn’t help anyway. Please feel free to reach out at “[email protected]”

Thanking You,
