Closed Issue: Error while using Crystal Reports with Ajax Control Kit .Net 2.0 [23490]

I had implemented the AutoCompleteExtender using Ajax Control Toolkit in Visual Studio 2005 for a Web Application. It was working fine and the compilation tag in web.config file was as follows:
<compilation debug="true">
<assemblies>
<add assembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
</assemblies>
</compilation>
Later I added a Crystal Report to the solution and the compilation tag was as follows:
<compilation debug="true">
<assemblies>
<add assembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
<add assembly="CrystalDecisions.CrystalReports.Engine, Version=10.2.3600.0, Culture=neutral, PublicKeyToken=692fbea5521e1304"/>
<add assembly="CrystalDecisions.ReportSource, Version=10.2.3600.0, Culture=neutral, PublicKeyToken=692fbea5521e1304"/>
<add assembly="CrystalDecisions.Shared, Version=10.2.3600.0, Culture=neutral, PublicKeyToken=692fbea5521e1304"/>
<add assembly="CrystalDecisions.Web, Version=10.2.3600.0, Culture=neutral, PublicKeyToken=692fbea5521e1304"/>
<add assembly="CrystalDecisions.ReportAppServer.ClientDoc, Version=10.2.3600.0, Culture=neutral, PublicKeyToken=692fbea5521e1304"/>
<add assembly="CrystalDecisions.Enterprise.Framework, Version=10.2.3600.0, Culture=neutral, PublicKeyToken=692fbea5521e1304"/>
<add assembly="CrystalDecisions.Enterprise.InfoStore, Version=10.2.3600.0, Culture=neutral, PublicKeyToken=692fbea5521e1304"/>
</assemblies>
</compilation>
When I run the report I am getting an error stating "request for the permission of type system.security.permissions.fileiopenmission, mscorlib, version=2.0.0.0, culture=neutral, publickeytoken=b77a5c561934e089 failed".
Please guide what is to be done to remove the error and run both the AutoCompleteExtender and Crystal Report.
Thanks in advance.
Comments: It seems that the described problem is not an Ajax Control Toolkit issue.
