E-Commerce Installation Error

Receiving error when connecting with mysql portion of install. Sometimes i get error 2 and now it's just running and running. I've tried changing database names, user name, passwords, etc to get something to work, but nothing has worked. i'd like to install with simple scripts, which always works, but I need the demo and sample data for this one. Is there a way to get all the samples and formats while uploading to an existing site? Or, does anything have a recommendation to the problem?

You must know CORRECT parameters for MySQL. Please ask your hosting provider about it.

Host reports that theres errors in the joomla installation files. They suggest to use simple scripts to install. Is there a way to create your full demo site if I do this?

Please use Report To Moderator and send us your FTP and MySQL access.

You forgot ftp username

You will have to consult your hosting provider about database engine and permissions. It is clear that your account can not create database with transact sql statements, so they probably know the best how they organised that . Also if you have option in control panel you can try to delete/create database again.
