I have no idea how to resolve this problem. I am appreciate anybody who can tell me what the problem is and how to solve it.

The process that i install the nopCommerce is:
1. upload the unzip files to host account
2. create the empty database
3. add connection string to the ConnectionStrings.config
4. excute the nopCommerce_createDatabase.sql file
5. type this url address to install, but got that error message.
