Error hosting asp.net website

I am hosting a aspx website on somee.com This is the error I am getting Error Summary:

HTTP Error 500.19 - Internal Server Error
The requested page cannot be accessed because the related configuration data for the page is invalid.

Detailed Error:

Module  IIS Web Core
Notification    Unknown
Handler Not yet determined
Error Code  0x80070032
Config Error    The configuration section 'configuration' cannot be read because it is missing a section declaration
Config File \\?\d:\DZHosts\LocalUser\schalla27\www.Thomasblog.somee.com\web.config
Requested URL   http://thomasblog.somee.com:80/
Physical Path   
Logon Method    Not yet determined
Logon User  Not yet determined

Here is my web.config

configuration>
  <system.web>
    <compilation debug="true" targetFramework="4.0"/>
  </system.web>

  <configuration>
    <system.web>
      <customErrors mode="Off"/>
    </system.web>
  </configuration>
</configuration>

What is the difference between hosting on iis and another free hosting site like somee.com

Thanks Sun
