Object reference not set to an

I developed the tests using the ComponentPro \ UltimateStudio v6.8.4155 \ Samples \ Saml \ Web \ CS \ ADFS \ ServiceProvider component in version v6.8.4155, but when I purchased the license it was sent to version 7.0.70, but this is giving error in the line : "if (assertion.IsSigned ()) // if the assertion is signed" from the ConsumerService.aspx page. When running the program the following error is displayed: "System.NullReferenceException: Object reference not set to an instance of an object.     at Adfs.ServiceProvider.ConsumerService.OnLoad (EventArgs and) "

We have sent v6.8 for your test. Please send us the adfs project to support@componentpro.com for our further investigation.
