Configuration System Failed to Initialize

I have the following config file:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <configSections>
        <sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >
            <section name="DLLLoadTest.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
        </sectionGroup>
    </configSections>
  <!-- Configuration section-handler declaration area. -->
  <configSections>
    <sectionGroup name="serverControlGroup">
      <section
        name ="serverControl"
        type = "ADMultiDomain.ServerControlSections"
        allowLocation = "true"
        allowDefinition = "Everywhere"
        />
    </sectionGroup>
  </configSections>
  <!-- Configuration section-handler declaration area -->
  <serverControlGroup>
    <serverControl controlKey = "1" controlName = "MurachWebControlLibrary.dll" description = "Server Control Test"
                   location = "C:\LOCAL_DEVELOPMENT\MurachWebControlLibrary\MurachWebControlLibrary\obj\Debug\"
                   method = "DaysUntilDate" />
  </serverControlGroup>

  <applicationSettings>
        <DLLLoadTest.Properties.Settings>
            <setting name="General" serializeAs="String">
                <value>"No value, used to generate app.config in proper format"</value>
            </setting>
        </DLLLoadTest.Properties.Settings>
    </applicationSettings>
</configuration>

And I am using the following to intialize my class to read from the app.config:

                DLLLoadTest.ServerControlSections config =
                    (DLLLoadTest.ServerControlSections)System.Configuration.ConfigurationManager.GetSection("serverControlGroup/serverControl");

And I get the following error, when this code tries to execute:

'Configuration System failed to initialize'

Any thoughts why.  I made sure that under the root I have configSections.
