Trying to install DNN4 (first time user) on Windows XP pro, IIS5 and SQL Express 2005.

The SQL instance is SERVER\SQLEXPRESS.

When opening DNN in Internet Explorer I get the following error:

Object reference not set to an instance of an object.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

Stack Trace: 

[NullReferenceException: Object reference not set to an instance of an object.]
   DotNetNuke.Common.Utilities.Config.GetConnectionString(String name) +47
   DotNetNuke.Data.SqlDataProvider..ctor() +126

[TargetInvocationException: Exception has been thrown by the target of an invocation.]
   System.RuntimeTypeHandle.CreateInstance(RuntimeType type, Boolean publicOnly, Boolean noCheck, Boolean& canBeCached, RuntimeMethodHandle& ctor, Boolean& bNeedSecurityCheck) +0
   System.RuntimeType.CreateInstanceSlow(Boolean publicOnly, Boolean fillCache) +103
   System.RuntimeType.CreateInstanceImpl(Boolean publicOnly, Boolean skipVisibilityChecks, Boolean fillCache) +261
   System.Activator.CreateInstance(Type type, Boolean nonPublic) +66
   DotNetNuke.Framework.Reflection.CreateObject(String TypeName, String CacheKey, Boolean UseCache) +230
   DotNetNuke.Framework.Reflection.CreateObject(String ObjectProviderType, String ObjectProviderName, String ObjectNamespace, String ObjectAssemblyName, Boolean UseCache) +571
   DotNetNuke.Data.DataProvider.CreateProvider() +39
   DotNetNuke.Data.DataProvider..cctor() +13

[TypeInitializationException: The type initializer for 'DotNetNuke.Data.DataProvider' threw an exception.]
   DotNetNuke.Common.Globals.GetUpgradeStatus() +324
   DotNetNuke.Common.Global.CheckVersion() +187
   DotNetNuke.Common.Global.Application_Start(Object Sender, EventArgs E) +316

The data connection parameter in my web.config is:

    <!-- Connection String for SQL Server 2005 Express -->
    <add
      name="Server"
      connectionString="Data Source=.\SQLExpress;Integrated Security=True;User Instance=True;AttachDBFilename=|DataDirectory|DNN.mdf;"
      providerName="System.Data.SqlClient" />

What am I doing wrong?
