JScript error when downgrading to .net 2.0

I have a problem with a Web Application project which I have created. Originally I developed it in .net 3.5 and everything was okay. I have since been told that it needs to be in .net 2.0 (sigh) which has not only caused problems with the LINQ stuff I had written but has now also created a weird JScript error. The error occurs whenever I click a button within an UpdatePanel. The error is in one of the ScriptResource.axd files. The error is: 

Microsoft JScript runtime error: Unable to get value of the property 'PRM_ParserErrorDetails': object is null or undefined

and occurs at line 

this._endPostBack(this._createPageRequestManagerParserError(String.format(Sys.WebForms.Res.PRM_ParserErrorDetails,parserErrorDetails)),sender);

The Pages are created using a MasterPage which is the Page that contains the UpdatePanel, along with an UpdateProgress control. Since changing to .net 2.0 this error has occured. When I changed it I added the System.Web.Extensions assembly to the web.config and also registered the controls from the same assembly. I have researched online and can't seem to find anybody with a solution or similar problem. Any suggestions or answers?

Okay as per usual I solved the problem almost instantly after posting. It seems the problem was that I was missing some sections from my web.config file. I had registered the controls using

<pages>
  <controls>
    <add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
  </controls>
</pages>

and also the assemblies using

<assemblies>
    <add assembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
</assemblies>

inside the system.web section but I was also missing:

<sectionGroup name="system.web.extensions" type="System.Web.Configuration.SystemWebExtensionsSectionGroup, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35">
  <sectionGroup name="scripting" type="System.Web.Configuration.ScriptingSectionGroup, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35">
    <section name="scriptResourceHandler" type="System.Web.Configuration.ScriptingScriptResourceHandlerSection, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="false" allowDefinition="MachineToApplication"/>
    <sectionGroup name="webServices" type="System.Web.Configuration.ScriptingWebServicesSectionGroup, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35">
      <section name="jsonSerialization" type="System.Web.Configuration.ScriptingJsonSerializationSection, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="false" allowDefinition="Everywhere" />
      <section name="profileService" type="System.Web.Configuration.ScriptingProfileServiceSection, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="false" allowDefinition="MachineToApplication" />
      <section name="authenticationService" type="System.Web.Configuration.ScriptingAuthenticationServiceSection, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="false" allowDefinition="MachineToApplication" />
    </sectionGroup>
  </sectionGroup>
</sectionGroup>

inside the configSections part in Configuration and also

<httpHandlers>
  <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>

</httpHandlers>
<httpModules>
  <add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
