Database error upon Moving site

Sure hope someone can help me. I think I'm almost there.

I'm moving a WPMU (fairly new installation so there is only one blog). It the same hosting company but different cPanel and domain. This is what I've done. (after I backed everything up)

I went created a new database at the new location.

I used an editor and changed the name of the database and site name throughout the sql file.

I ftp'd all of the WP files into the new site. I verified the wp-config file and made sure the username an pw were correct.

Everything seemed to upload without any problem. However I get an error that says "Error making a database connection"

Where else can I check? (My hosting company was to move this last week and it was a nightmare. So I'm doing it myself) Right now the domain is redirected to the test site so lat least they have something.

Any other files I forgot maybe?

Thx,

Sleenie
