Installing CSM made easy on Yahoo's webhosting service, stuck on step 3

[Zgoal]

Hi Everyone!

I am trying to install CMS made easy on a website I ordered from Yahoo's webhosting service.  I loaded CSM Made Easy onto my Yahoo website, and can't get past step three.  I keep getting the message: Could not connect to database. Verify that username and password are correct, and that the user has access to the given database.

I followed the CMS instructions and created the following in MySql:  create database cms; (use whatever name you want here but make sure to remember it, you'll need to enter it on this page) then grant all privileges on cms.* to cms_user@localhost identified by 'cms_pass';

This is how I answered the following questions for step three

Database Type:                                   MySQL (3 and 4.0) 
Database host address                          mysql (Yahoo told me to use this)
Database name                                   cms
Username                                           I tried my used name and the user name CMS told me to set up
Password                                            I tried mine and the one that CMS told me to use
Table prefix                                         left blank     
Create Tables (Warning: Deletes existing data)     left checked
Install sample content and templates                   left checked

Any help would be greatly apprecatied!

Thanks,
Mark

Data base host address needs to be something.something.TLD, at least in mine, like.

34095.prformance.net

DB name needs to be specific, at least in mine.

dbu4953204

The user name came from my host.

dbou4953204

Password was supplied when I setup the DB.

WzX3DrtUV

All the above names have been changed to protect the innocent, when I set up the DB I was given this info.
